When studying
how forces act on an object, a Computer Aided Design (CAD) application
program can be very useful in determining the overall magnitude
and direction of the resulting force on the entity. In previous
years, individuals having knowledge of this Engineering technique
would find each subcomponent leg of a force that fell on the
X, Y and Z axis and they could be added or subtracted based
upon their direction and therefore deriving a total answer in
all three axis, the resultant force acting on the body is then
found. The long process to locate the sub-vectors involves the
using Trigonometric functions such as Sine, Cosine and Tangent.
To set up such a mathematical problem requires us to visualize
the problem, so we can use the correct formula to evaluate the
force distribution. Any errors in sketching, from poor hand
and eye coordination ending in a sloppy illustration, or from
a minor flaw in the mathematical calculation would give the
designer an incorrect conclusion. In our experience, many professionals,
avoid the lengthy computations and send them out to other experts.
Many project managers appreciate visual design and have never
really enjoyed the hand written math problems many of us are
taught in school.
