Prof. Uday Amonkar ----- An Unsung Hero of Engineering Education
I still remember those days in the Goa Engineering College hostel. I was in my Third year B.E
then. Till late nineties, Goa Engineering College was the only college available in Goa for the degree
aspirants that time. Studying in the Hostel had a different style of its own. You stroll the entire day
and sit to study in the depths of the night as if the knowledge Gods were freely distributing their
blessings on the students in the nights. Sharing what you gather from wide variety of books with
others made everyone wise.
Every night in the Hostel one Common man was seen, average personality, didn’t seem to use a
razor for shaving, his eyes covered with thick glasses, He was a great thinker and analyser. He was
indeed that Knowledge God coming as a savior to the students. He was none other than Prof. Uday
Amonkar. Anybody having any doubts in any of the subjects of Engineering, Amonkar sir was there
to help him. Scholars and intellectuals used to search him out for advice. Our studies were under
the banner of University of Bombay and our papers were set by reputed teachers from VJTI and
SPCE colleges. It was a tough task to even understand the questions, forget about answering them.
Shri Uday Amonkar had joined teaching profession soon after passing his B.E. with a clear intention
of pursuing his post graduation studies in Industrial Engineering. But like a Good Samaritan, he used
to devote his time and experience with the prospective engineers.
My tryst with Sir came though a funny incident. Happenings were round the corner in the month
of January 1988. We the gangs of Bardezkars were sitting in our room after having feast in the
hostel mess. All of a sudden a strange person in his early twenties entered our room. He introduced
himself and later on told us that tomorrow onwards he will be taking us lectures in the elective
subject. We all were surprised as no college or university professor would have introduced himself
to his students in this manner. Uday sir was like that, simple, uncanny and unconventional. There
was no ego, there was no pride, always thought of his students and his studies. I could see his
devotion even while teaching a subject of less importance in comparison to the core Mechanical
Engineering stream subjects.
One day, I just asked him one personal question, only because he was more than a friend,
philosopher and a guide to me. I told him one girl is frantically following me, she doesn’t seem to
leave me. She follows me wherever I go. Sir laughed and said she must be beautiful like you. What
beauty, she is nowhere compared to me, I said to myself. Reading my face, sir said I will ask you
one simple question you reply that question properly. I will give one utensil of gold but it is filled
inside with cow dung and I will give you another utensil which is made of cow dung but is filled with
gold. Which utensil you will prefer? Before giving the reply I could realise what sir wanted me to
realise. I knew my ego level was high when I thought about that girl. The question made me
understand the reality of life and even influenced my decisions in life.
Now, even after the good old days of studies and books and the golden years at Farmagudi, as I
entered the world of work, 3 years in Industry and later on I too joined teaching field, I could garner
inspiration from Amonkar sir on many occasions when we used to come across each other on
numerous occasions for seminars, symposiums and conferences. When in industry, I tried to pursue
Volume 3, Issue 1, May 13, Mechanical Engineering Department, GEC

my higher studies when sir gave me confidence how to achieve it amidst busy schedule. I failed to
stick to ME and the Industry job as it offered less perks and it used to keep my purse always empty.
Today, after putting in 22 years of service in teaching, I have seen so many professors who come
with high qualifications but work for their own self. In this IT age where information is available to
students on one finger touch, many of the teachers use multimedia like OHP, LCD, tablets & laptops
to teach the students but never correlate with student’s mental & emotional level. Amonkar sir
never did that. He created his own multimedia lessons through relentless striving. He made these
CDs & DVDs available to his students of Masters in Industrial Engineering, so that they should not
loose touch with the essence of knowledge. He used chalk & talk method to the best possible
advantage.
In his personal life and on the health front, he faced lot of hardships. He did not enjoy a very
good health, but despite odds he was a classic example of courage and dedication to duty. He
began his routine day at work at 9 am in the morning and continued till 10 pm in the night teaching
BE and ME students with equal gusto and devotion. Whenever and wherever he met his students,
his sessions used to start there, maybe it is library, canteen, and roadside shade or even in a car. At
times he used to postpone his appointments with the doctor since he had viva-voice scheduled for
the students.
Master programme in Industrial Engineering was his forte and he excelled in the same
exceedingly well. Though, I was not a student of M.E. in Industrial Engineering (which I consider my
misfortune as I missed Amonkar sir’s blessing as a guide), I have gathered lot from my colleagues
who did and were doing ME in Industrial Engineering under his stewardship. With his uniqueness
he had carved a niche for himself and the ME programme to the extent that M.E. in Industrial
Engineering had become synonymous with Prof. Uday Amonkar.
All was well until that evening of 21st Janaury 2013, when I received a SMS informing his death at
GMC in the evening, I was shell shocked. He was admitted for difficulty in breathing 2 days ago. He
only leaved his half life. For the 50% life you leaved you gave 100% to your work and your love for
teaching. They say those who die young are liked by God. It was very true in your case. Sir you have
not died but lived forever in our hearts. We will miss you and probably may not find a professor like
you for many years to come. May your beloved wife and daughter get the courage to carry on your
good work. God bless your soul.

Industrial Estate- Goa, India. The students were given a guided tour of the plant, where they
witnessed activities spanning various domains such as Inventory control, manufacturing, storage,
assembly, testing and dispatch. The students got an opportunity to see various CNC machining
operations, surface treatment processes, and manual assembly operations in action. Some of the
special machines which they got to see were the 3-axis HNC and VNC, the special lathe used for
manufacturing of the lobe drivers for the pumps. Various quality and production monitoring
systems were also in place. Students also got an insight into efficient plant layout techniques in use
in the industry. To summarize, the visit gave the students the opportunity to see how the theory
studied in the classroom translates to practices in the industry.

Field Visit: ASTRA METALS, Verna Date : 27th Feb 2012 Timing: 9.30 am to 1.00 pm
Visiting Students: SE Mechanical (67 students)
Faculty : Prof. Tanay Rege & Prof. Pratik Sawardekar , Assistant Professor
We, the students of SE mechanical class were taken to Astra Metal Works, Verna for our
industrial field visit. It is a fabrications company that primarily deals with the production of
precision sheet metal components and assemblies. These products are totally custom made in
accordance with the customer’s specifications.
When we arrived at the location, we were greeted by the manager Mr Rohit who also
guided us through the site and explained and demonstrated in detail the various processes that
were carried out.
The first operation that was demonstrated was the punching operation. This was done on a CNC
operated machine on which punches of the required dimensions were mounted. These punches
were spring loaded so as to absorb the shocks of the impacts when the punches were hydraulically
driven through the sheet metal. The springs protected the machines from incurring any damage.
This machine is largely automated, except the positioning, which is required to be done manually.
The job requires only 2 employees which makes it very efficient. The rest of the operation is
controlled by a computer, to which data has to be input in the form of g-codes. The data must
consist of the thickness of the sheet, dimensions of the hole, sequence in which the punching has to
be carried out. The maximum amount of load the machine could handle was about 30 tons and
sheets which were 4 cms thick could be worked on.
The second operation was the laser cutting operation. Again a CNC machine was used that
employed an oxygen- gas based laser. The laser beam was cumulated to a very fine one. The laser
torch (liquid cooled) could be moved along the y and z axis (sideways and up-down) whereas the
sheet metal has to be moved along the x axis. The metal sheet was operated on a platform which
had rollers on it to facilitate the movement of the sheet. The thickness of metal that could be cut
Volume 3, Issue 1, May 13, Mechanical Engineering Department, GEC
7
was about 8 cms. Any dimension desired can be cut out. The machine was again controlled by
computer which required the data in the form of g-codes.
Next, we were shown the bending operation. The machine was again a CNC machine that
was hydraulically powered. It had 2 jaws, the upper jaw was fixed and the lower jaw was kept
movable for convenience. The g-code now commanded the machine to bend the sheet at a
required angle, and also maintain a required flange, etc. employees were required only to support
the sheet from bending unnecessarily on account of its weight. The jaws spanned 3 mts across.
The computer that monitored this machine had a memory so that a series of sheets that
required the same amount of bending could be worked on, without the need of entering the g-
codes over and over again. It also facilitated the sequence in which a series of bending operations
with different data could be carried out. So G-codes of about 20 ops could be feed at once and then
worked on. There was also a miniature machine of the type described above. This one however was
manually operated, was one Mt long and had no computer controlling it. Small jobs could be done
on this machine. The whole idea of using automated machines was to just ensure accuracy. The
customers place their orders in the form of a CAD model or hand drawing with proper dimensions.
In the former case the CAD model can be directly converted into a form that the machine
understands, that along with the g-code has to be entered during operation. In the latter case some
of the employees constructed a CAD model out of a drawing and the rest of the process is as above.
Then the next operation was the welding operation. ASTRA METALS preferred MIG type
welding for their product as it was less expensive and the welds were strong and free of impurities.
The process is almost the same as arc welding. Only that the consumable electrode is copper which
is wound on a reel that is driven by a motor. And inert gas flows through the torch to prevent
oxidation of the weld. The operation however demands skilled and experienced employees. The
finishing was done by hand grinders.
The next step: tank treatment. This treatment removed surface impurities and readied it for
coating. It is a 9 step process. The jobs are supposed to be kept in a sieve that is mounted on a
crane. And the crane dips this sieve in different tanks. The first dip is for degreasing purposes and
uses gardoclean 444 for that purpose. The second dip simply rinses the sheets clean. The third
the surface and the 4th tank rinsed it. The 6th tank process used gardalene 21 which
neutralises the surface and the 7th rinses it again. The 8th process was for triphosphating the surface
using a zinc phosphate compound and the final tank was for passivation on the metal surface. This
was done with gardolene NLD-6800. For quality purposes the chemicals are replaced periodically.
The above tank treatments are done to ready the surface for coating. The sheets are hung in
booths for coating. Provisions are made to ground the booth and hence the metal sheet. This
ensures that the powder coating, which is positively charged with respect to the sheet, will stick.
The powder is sprayed on the metal with the help of a gun. Once it is coated it is baked for 20
minutes at 200 degrees. This melts the powder and gives the surface a uniform finish. The texture
depends completely on the type of powder used. Some good quality but expensive powders give a
smooth finish with a glossy look for example. The powder that is not used in the booth is sucked in
by centrifugal pump. This pump also separates the lighter particles (<50 micron) from the heavier
ones.

Then finally the coated baked sheet is varnished on the areas where it is not coated to prevent
corrosion. Then it is allowed to dry and then delivered to the customers.
To summarise, we have learnt how sheet metals are cut and shaped as required using
powered automated machines, and how these parts are joined together, how the surface is readied
and coated, all on the industrial scale.In this field visit we have learnt a lot of new things about
industry and metal works in a very enjoyable way.

TORQUE - 2013
Report by M. AGNEL XAVIER FERNANDO (BE Mech )
The Mechanical Engineering Students’ Association of Goa College of Engineering(GEC), Farmagudi,
Ponda organised their annual two day national level technical festival “TORQUE 2013” on the 14th and 15th
of March 2013 in the college campus. TORQUE was held for the fourth successive time in the college. Over
the years it has grown bigger and better with students coming not only from GEC but also from other
colleges in and outside Goa to participate and witness the event.
The event started with an inaugural function on 14th March 2013. The Chief Guest for the inaugural
function was Shri. Vivek Kamat, Director of Technical Education, Goa. The other dignitaries included Prof. R.
B. Lohani, Principal GEC, Prof. Rajesh Prabhugaonkar, Head of the Mechanical Engineering Department, GEC,
Prof. Milind Sakhardande, Staff Advisor of the MESA Council, GEC and other teaching and non-teaching staffs
from the Mechanical Engineering Department and faculties from other Departments. A large number of
students attended the function. The function started with the declaring of Torque 2013 open by the Chief
Guest Shri. Vivek Kamat. -This was followed by the garlanding of the portrait of ex-HOD of the Mechanical
Department Late.Prof.Uday Amonkar. Thereafter the specially designed TORQUE 2013 t-shirts were
launched at the hands of the chief guest and the Principal.
The Chief Guest while addressing the gathering stressed that a national level event like TORQUE
provides a platform for the young minds in the different engineering colleges and gives them an opportunity
to think out of the box. He wished good luck to torque 2013 and also started the proceedings by trying out
the Robo control.
The two day festival included events divided into two categories – Technical and Techno-Fun. The
major attraction in the Technical category was RoboWars. As the name suggests it was a fight between
robots on the specially designed arena. In this event, students had to build a robot on which were attached
the weapons. There were three rounds in total and each match had three robots fighting at a time. About 40
teams from GEC and other colleges from Goa and outside the state participated in the event. The
enthusiasm from the audience gathered around the arena added more fun to the event. As each robot hit
the opponent the claps and cheers from the crowd made it an even more exciting contest. Tyres came off,
Motors got burnt but still the war continued. Not just the make of the robot, the technique also mattered.
RoboRace was an event in which the students had to complete the lap on the track made for the
event using the robot built by them for the same. This time it was an all terrain race which included
obstacles in the form of stones, leaves, sand and oil. The criterion for judgement was the least time taken
for completing the track. About 10 teams from various colleges participated in the event. The way the robots
were controlled on the slopes, bridges and over the obstacles was amazing. There was another event called
as Catapult. The aim of the event was to test how precisely a participant can give an impulse to the ball so
that it hits the given target accurately. For giving the impulse the participant had to build a launcher for
launching the ball. The event tested the knowledge of projectile motion. Event saw healthy participation
from the students.
Line Follower was another event in the technical category wherein the robot that was constructed
by the students had to trace a black line. The robot was programmed by the students to perform the
intended function. The criterion for judgement was least time taken to cover the entire line follower track.
Volume 3, Issue 1, May 13, Mechanical Engineering Department, GEC

The next in line in the technical category was Amphibian. As the name suggests, in this event
students had to build a robot that could go both- on land and water. The robot had to cover the track that
was constructed for the purpose. The entire track had some portion on land and some in water.
The next category was the Techno-Fun. This category too included many events. RoboControl was
an event in which a participant had to drive the robot constructed by the torque team on a track that was
designed for the purpose. The person to complete the track in the least possible time was adjudged the
winner at the end. The event drew many participants who were very excited to control the bot and drive it
to the finish line crossing over the obstacles in the path.
An interesting event introduced in Torque 2013 was ROBOFOOTBALL. Here 4 robots in a team of
two designed by the organisers played a game of football in the specially designed arena. These robots were
controlled by the participants. The team that nets the maximum number of goals was adjudged the winner
of every match as is the case with football. The event saw wide range participation from students within the
college and outside. There was a large crowd of students around the arena who were cheering and clapping
as each team tried to net the ball in the opponent’s goal. There was an event called as Touch-Me-Not
wherein the participant had to pass an l looped metal wire from one end of a thick wire to another without
touching the wire.
Other events included Paper Presentation wherein students from various colleges presented their
ideas in the form of a paper. There was no restriction on the branch to which the students belongs to. As a
result of which there were many participants from outside the state also. There was aptitude test also which
tested the students’ logical reasoning skills. This event drew wide participation from the students who
eagerly came forward to get their skills tested. An event called psychometric test was also introduced for
the first time in Torque 2013.There were Quiz, Auction Ville wherein the students had to squeeze their
brains to get the answers right.
One of the major crowd pulling event was the AIR SHOW that was held on 14th March 2013 for the
first time in Goa by trained professionals from Pune. A total of 15 planes were flown. The students were in
for a treat as the acrobats shown were of real high class and a delight to watch. The air show lasted for
almost one and a half hour. At the end of the session the students gathered at the ground looked satisfied
and mesmerized having witnessed something really new and awesome. It was an additional boost for
Torque 2013. Another event introduced in Torque 2013 was the Military Simulation, MilSim in short that
was held on 15th March 2013. It was nothing other than the real time military simulation game wherein
twelve participants divided into two teams of six each fought a battle in the arena made for the event. The
safety of the participants and spectators was of prime importance. The participants were provided with
special suits to protect their body and eyes from the paint balls. A net was provided all around the arena for
protecting the spectators from getting hit by the paint balls. The participants said that it was a very exciting
event n similar was the response from the spectators.
The overall response from the participants and the spectators about Torque 2013 was very positive.
Torque 2013 took Torque to the next level.
Undoubtedly Torque 2013 was highly successful..
Wishing good luck for Torque in the years to come.

Experimental Aluminium Casting Raunak Kamat and Neil Almeida, students of SE Mechanical
Engineering, GEC and Akshay Badami, Leroy D’Souza and
Anant Shirodkar, of PCCE Verna Goa came together to
experiment a casting using Aluminium. The mould was made
of locally available clay, sand and brake fluid was used as a
binder. The pattern was made out of thermocol. The furnace
was designed and built locally by the students, using a large
tin lined with concrete. It had two holes, one through which
air was supplied via an old vacuum cleaner, and the other
through which molten metal was to flow out. Wood was
used as fuel to melt the metal. The casting was obtained
with substantial defects due to inexperience and improper
conditions.

KEYBOARD - A MUSICAL INSTRUMENT
M. Agnel Xavier Fernando
A keyboard is an electronic or digital musical instrument. The major components of a typical
modern electronic keyboard are:
Musical keyboard: The plastic white and black piano-style keys which the player presses, thus
connecting the switches, which triggers the electronic note or other sound. Most keyboards use a
keyboard matrix circuit to reduce the amount of wiring that is needed. It has user interface
software.
Rhythm & chord generator: A software program which produces rhythms and chords by the means
of “MIDI” electronic commands.
Sound generator: An electronic sound module typically contained within an integrated circuit or
chip, which is capable of accepting “MIDI” commands and producing sounds.
Amplifier and speaker: a low-powered audio amplifier and a small speaker that amplify the sounds
so that the listener can hear them.
Everyone has some talent. I had an interest in music right from a very young age. My parents
recognised my talent in music and encouraged me to develop it in life. I thank them and also thank
my music teachers.
I love composing new tunes and also reproducing the filmy tunes after hearing them. It is also an
excellent hobby as it helps in refreshing my mind whenever I am stressed out and tired. It played an
important part during my school days as I won many awards and prizes because of music.
I love music and more than anything else I love my keyboard (YAMAHA PSR 78) which is there with
me for the past 14 years. It is like my younger brother and my best friend at home.

Photography by Roshabh Mayekar
I bought my first digital SLR in 2010 and started to "snap"
photos. I learnt photography from ace photographers Ashish
Parmar, A.B. Apana & Assavari Kulkarni. Since then I have
been on a wonderful journey exploring my creative side. Due
to my engineering studies, I don't have as much time to
devote to photography as I would like, but I still get to spend
a lot of time on it. So I guess you can say my career as a
photographer is just beginning. I have taken maybe 10000
photos since 2010.Due to my strong technical background I understand most facets of optics and
sensors. I can use this knowledge to get the most out of any situation. This gives me the advantage
to focus more on the creative side of photography, which I have been trying to improve during the
last year or so.
Some tips on wildlife photography Wildlife subjects can be divided into two categories: wild and under human control. Pursuing both can produce wonderful images. Of course, there's nothing more exciting than capturing a spectacular image of a wild animal in its natural environment, but many times it's not possible to travel to exotic locations or spend days or weeks tracking an animal. What's more, many animals are extremely dangerous. How to Shoot Wildlife Photography: Close-up vs. Environmental
It's not necessarily desirable to always get full-frame head shots of wildlife - you can always take
head shots in a zoo. Including the environment along with an animal gives a sense of place, and if
the location happens to be spectacular then it becomes an integral part of the composition. Still,
the subject should be significant enough in the frame to make a statement.
How to Shoot Wildlife Photography the Right Way: Keep Things Steady
In addition to doing your wildlife photography in the best light, I strongly suggest using a tripod
whenever possible. When photographing with a tripod is not possible, use a bean bag or some
other stable support. Image stabilization lenses, if you can afford them, go a long way to helping
wildlife photographers get sharp pictures in low light. They minimize camera movement when you
hand hold them, which in turn gives you more flexibility in your shooting. However, I would still
recommend a tripod when it's feasible.
How to Shoot Wildlife Photography from a Vehicle
In many cases, a vehicle can gain a closer approach to a wild animal than a person can on foot. For
example, most wildlife in national parks have grown accustomed to vehicles, and they know there's
no threat. Shooting from a vehicle can be done using a stable platform that attaches firmly to the
driver's door when the window is rolled down. You can also use a burlap or fabric pouch filled with
uncooked rice, beans or coarse sand. This actually is my preferred choice for shooting from a
vehicle. I travel with it empty, but when I arrive at the shooting destination I'll fill it.

“ L I F E ” by M. Agnel Xavier Fernando, BE Mech Life is a race, which all don’t complete,
Whatever be the case, fearlessly you should compete,
You may win or you may lose, but never give up,
Face the toughest of challenges by just showing a thumbs-up.
No and impossible are the words often used by cowards,
Why to worry if you have real good friends,
With full guts and will, face the challenges,
Don’t think much about what would be the consequences.
You may fail, but remember it’s a step towards success,
Get up and march ahead, with renewed energy and confidence,
If you work hard, the result will never be fruitless,
Concentrate about the present without thinking much about the past and future.
Lend a helping hand for someone who is in need,
Because it’s nice to travel with someone in this journey of life,
Try to bring a smile to someone’s face,
It will give you immense happiness and a reason to smile.
Respecting others is something you should never forget,
Only if you know to respect, the similar respect you will get,
Enjoy your life, don’t worry just be happy, my best wishes for your future buddy...!!!
