Example:

Assune that suspended load is 1000 pounds located at (x,y,z,)
coordinates (50,-50,50)

Coordinates,Point 1 (80,-50,170)
Coordinates,Point 2 (35,-24,110)
Coordinates,Point 3 (35,-76,150)


Results:

Length 1= 124   Tension 1 = 442
Length 2= 67     Tension 2 = 240
Length 3= 104   Tension 3 = 373
