Textbook Question

Chapter 7, Problem 8AP

8. How much tension (F_m) must be supplied by the triceps to stabilize the arm against an external force (F_e) of 200 N, given d_m = 2 cm and d_e = 25 cm? What is the magnitude of the joint reaction force (R)? (Because the forearm is vertical, its weight does not produce torque at the elbow.) (Answer: F_m = 2500 N, R = 2700 N)
