Statics of Rigid Bodies

Solve the following problems. F-30 lb 1. The foot segment is subjected to the pull of the two plantarflexor muscles. Determine the moment of each force about a point of contact A on the ground. Ans: Mo = -139.71 lb· in F- 20 Ib/ 70 4 in. 900 mm 700 mm 300 mm -3.5 in- 2. An experimental device imparts a force of magnitude F = 225 N to the front edge of the rim at A to simulate the effect of a slam-dunk. Determine the moments of the force F about point 0 and about point E. Finally, locate, from the base at 0, a point C on the ground where the force imparts zero moment. 3050 mm Ans: Mo = 123.8 N- m CCW; MB = 166.5 N- m CW; d = 688 mm left of O
