How much tension (F m ) must be supplied by the triceps to stabilize the arm against an external force of 200 N, given d m = 2 cm and d e = 25 cm as shown in the textbook What is the magnitude of the joint reaction force (R) (Since the forearm is vertical, its weight does not produce torque at the elbow.) (F m = 2500 N, R = 2700 N)
