Question
2a please help me with the answer and full solution
An experimental device imparts a force of magnitude F = 41 lb to the front edge of the rim at A to simulate the effect of a slam dunk.
Compute the moment of the force F about point O and about point B. The moments are positive if counterclockwise, negative if
clockwise. Finally, locate a point C from the base at O to the location on the ground where the force imparts zero moment. The distance
d from point O to point C is positive if C is to the right of O, and negative if to the left.
Assume a = 36 in., b = 28 in., h = 12 in., H = 10 ft, c = 2, and d = 3.
