Question

A 500-lb load hangs from three cables of equal length that are anchored at the points (-2,0,0), (1,3^{1/2},0), and (1,-3^{1/2},0). The load is located at (0,0,-2*15^{1/2}). Find the vectors describing the forces on the cables due to the load. What is the vector describing the force on the cable anchored at (-2,0,0)?

Step 1

It is given that a load of 500-lb is hanged from three cables of equal lengths that are anchored at the points say, *A*,* B* and *C* respectively as shown.

Step 2

The point at which the load is located say D is,

Step 3

Note that, each cable is holding a weight of one third of 500 lb making an angle of 30 degree with the...
