The below figures a) shows the elbow joint in which the humerus bone in contact at two points A and B. The joint simplified as shown in figure b). The weight (W=20 lb)acts at the center of the circle. Determine the maximum force P that can be applied to the humerus bone without causing it to rotate. The coefficient of static friction between the humerus bone and the surfaces of the other bones at point A and B is μs=0.3. The radius of the circle is r=1 cm .
