The bar OA is fully constrained at O and attached to the cable AB.
The bar length is 20', and it forms a 30° angle with the z-axis and its
projection on the x– y plane forms a 60° angle with the x-axis. The point
B is prescribed by the coordinates (8',16',0). If the force in the cable is
2000Lbs, what is the moment of this force about O? What is the moment
of the 2000Lbs force about the axis OÁ.
