ENG 205 CE-ME-MECE-MSE HORIZONTAL AND VERTICAL
MEASUREMENTS
Slide 2
Vertical(adj.): going straight up or down from a level surface
or from a top to bottom in a picture etc. Syn: perpendicular
Vertically (adv.) Horizontal(adj.): parallel to the ground or to
the bottom or top edge of something. Horizontally (adv.)
Slide 3
e.g: If you place vertical lines next to horizontal lines, the
difference between the two is 90 degrees. e.g: You can use
horizontal and vertical lines as a guide when editing your
drawings. e.g: The depth of a lake is measured vertically from the
surface of the water. e.g: Measure the aircrafts body horizontally
to learn how wide it is.
Slide 4
What is dimension? Dimension is a measurement of something in a
particular direction, especially its height, length or width. Abbr.
Dimension - dim Dimensions - dims. e.g: Dont forget to measure the
dimensions of the shelves so that they fit securely into the
cabinet. e.g: An average football pitch has the dimensions of 105m
by 68m.
Slide 5
What is the difference between 2D and 3D? in a 2-D picture the
objects look flat rather than solid. in a 3-D picture, the objects
look real and solid instead of looking like a normal flat picture.
(depth as well as length and width.)
Slide 6
Linear Dimensions Linear dimensions, or linear units, measure
the distance between two points. Since two points define a line,
the units of distance are sometimes called "linear" units or
dimensions. Some linear dimensions are centimeters and inches,
meters and feet, kilometers and miles...

Slide 8
Vocabulary items Measure (v): to find the size, quantity, etc.
of something in standard units. Measuring something puts the amount
of the thing into numbers. e.g: The area in front of our house was
measured yesterday. Its 1 kilometre by 2 kilometres. Measurement
(n): The act or the process of finding the size, quantity or degree
of something. e.g: In order to reduce measurement error, take
several measurements and compute their average. e.g: The exact
measurements of the room are 3 metres 20 by 5 metres.
Slide 9
Vocabulary items Plane (n): a flat or level surface or an
imaginary flat surface which continues in all directions. Vertical
Plane: a plane that passes through a vertical line. It is
perpendicular to the ground. Horizontal Plane: an imaginary plane
which is at a right angle to the vertical plane. It extends
horizontally.

Vertical and Horizontal Planes
Slide 11
Vocabulary items Span (n): 1) the distance between two points.
2) The part of a bridge between one vertical support and another.
e.g: In 1955, a two-span bridge was built to carry trains across to
the river. a single span bridge a two-span bridge
Slide 12
Vocabulary items Wingspan(n): the distance between the end of
one wing and the end of the other when the wings are fully
stretched. e.g: The green glider has a wingspan of 9 meters.
Slide 13
Vocabulary items Width (n): the distance across something from
one side to the other. E.g: The additional cabin width offers
passengers wider seats and more aisle space. I___cabin(internal)
width___I
Slide 14
Vocabulary items Extremity (n): the furthest point, especially
from the centre. E.g. An extra engine was installed at the rear
extremity of the aircraft. Thickness (n): the size of something
between opposite surfaces or sides. Syn. Width E.g. The walls are
at least two feet in thickness.
Slide 15
Read the web page (dimensions of Airbus A380) in the book and
answer the questions. What is overall length? Overall Length is the
measurement which is taken between the two points that are furthest
apart, along the length (the whole distance along it) of the
aircraft. How is the overall height of an aircraft measured?
Overall height is measured vertically between the underside of the
wheels and a horizontal plane touching the top of the tail.
Slide 16
How is external width (maximum fuselage width) measured?
External width of an aircraft is measured horizontally between
vertical planes touching the outside faces of the fuselage
(body).
Slide 17
Dimensions of an aircraft A ? B ? C ? D ? A - Overall height B
- Wingspan C - Maximum fuselage width D Overall length
Slide 18
Vocabulary items Level (adj.): horizontal and flat. E.g: I
couldnt place the theodolite properly because the ground was not
level. Incline (n): to lean or slope in a particular direction.
Inclined (adj.): sloping; at an angle. E.g: In this picture the
surface has an incline of twenty degrees.
Slide 19
Vocabulary items Plumb (adj.): exactly straight, usually
describing a vertical surface or line. E.g. When you hang a door,
you need to make sure that it is both level and plumb. Out of
plumb: not straight vertically. E.g. Tower of Pisa is about 15 feet
out of plumb.
