Orthographic View depends on relative position of the object
to the line of sight.
Two dimensions of an
object is shown.
More than one View is nee-
to represent the object.
Three dimensions of an object is show

that each View show an object in two dimensions.
2. Axcncmetrfc drawing
that show all three dimensions of an object in one View.

- Perspective projection is not
used by engineer for manu-

The connecting rod of this slider-crank mechanism is a
two-force member. This observation simpliﬁes the solution
to the problem. The reaction forces at A and B must be in
equal but in opposite directions. These react

Consider a region in the plane of area A. We can think of the region as a thin plate with uniform thickness
and density. The centroid of the region has coordinates (x, y). It can be found using
