Program: Statics
By: Ben Axelrod

    I can’t think of another application of this program other than a Statics
class.  What it does is: you give it a direction vector (this does not have
to be a unit vector) and the force of this vector.  Then the program makes a
unit vector out of the direction vector then multiplies it by the force.  It
isn’t hard math but it takes a while to do these basic calculations.  NOTE:
if you enter the force as 1 you can get the unit vector.

Here is the formula used:

       AI  +  BJ   +   CK
(F)  -----------------------
     sqroot(A^2 + B^2 + C^2)
