Document Summary

Extra problems: consider an arm being held horizontally. Assume that the arm is stationary and rigid. The weights of the upper arm, forearm, and hand are 4, 3, and 1 kg, respectively. What are the joint reaction forces and joint reaction moment now: is the joint reaction moment a flexor or extensor moment? (a) answers: Joint reaction moment = 16. 9 nm (b)flexor (c) answers: Joint reaction moment = 25. 1 nm (d) flexor. Calculate the center of gravity of the thigh using the proportions from dempster"s. Table (see notes) given that the segment length is 41 cm. Calculate from both the distal and proximal end. Use the proportions in dempster"s table (see notes) to calculate the thigh weight of a person with a mass of 80 kg.
