Skate park Proposal

Leader: Liu Du Kai YingMember: Nicholas Lim Dexter Kuah

Name Venue Material Design Cost

Criteria

SC stands for super crazy This is to tell students to not only study like

crazy, but should also learn to play like crazy Furthermore, they can also revise their physics

components while playing

SC skatepark

Beside the basketball court Most of the time, not all courts are used at the

same time Convert one court to become a skatepark Noise generated would be same as that of

people playing basketball Far enough from classrooms Aesthetically, since the basketball grounds are

concrete, the colour of the skatepark would be very similar, thus blending in

Venue

Easily accessible, just beside canteen Basketball court big enough

Dimensions: 84 feet by 50 feet Dimension of proposed Skatepark:

55 feet by 35 feet http://www.basketball-goals.com/basketball%20court%20dimensions.htm

Venue

Surface: Masonite

Reason: Smooth skateboard/inline surface, thus reducing friction between the surfaces

Generally cheaper than the other common surfaces like metal and concrete

Can last 1+ year outdoors, thus reducing maintenance fees as only need to maintain once a year

Materials

Body: Plywood

Reason: One of the cheapest materials Easy to assemble and very available, thus

making it very cheap http://suburbanrails.com/cgi-bin/WebObjects/PWDA.woa/wa/loadPage?pageId=2013

Materials

The skate park design accommodates to both

expert skaters and beginner skaters There will be steps leading up to the right side

of the skatepark By starting on the high end on the right side,

one can enjoy the thrill as there will be some “air time”

By starting at the lower end on the left side, beginners then can safely move to the other side

Design

Split into costs for body and costs for surface Body:

A 10,000 Square Foot Wood Skatepark would cost between $8,000 to $25,000 per 1,000 square foot

Pricing is based on quality So, pricing of wooden body would range

between : ((35*55)/1000) * 8000 = $15400 ((35*55)/1000) * 25000= $48125

Cost

Surface:

Masonite siding costs $1 to $2.75 per square foot

So costs for our surface would be : (35*55) * $1 = $1925 (35*55) * $2.75 = $5293.75

Cost

In our skate park, the energy acting on

participants will go as follow: Let us label the highest point on the right as

“A”, the bottom point on the right as “B”, the peak of the center as “C” the bottom of the left as “D” and the peak of the left as “E”

Energy

A:

Gravitational potential

B: Kinetic, friction

C: Kinetic, Gravity, Friction

D: Kinetic, Friction

E: Gravity

Energy

Initial potential energy= mgh

(75)(10)(8.04) = 6030 J Friction Coefficient: 0.3 – 0.4 ( about the same

as wood with metal of the wheels ) Friction = 75 * 0.4 = 30J Amount of kinetic energy converted = 6000 J

Calculations

Before skating, all skaters should always wear a helmet Ensure that:

The helmet is made of a strong and durable material. Make sure that it is a skateboarding helmet, not a bicycle helmet. Bicycle helmets are made of thin materials that crack upon impact

The helmet should have protective pads known as Expanded PolyPropylene. This soft pad absorbs the damage when there are impact, thus protecting the skater

Safety Precautions

The skater can also wear elbow and knee

guards This ensures less friction between the surface

and the skater thus preventing abrasion The skater should wear wrist guards to

support the wrists in case he falls, because there is a tendency to land on your wrist.
