Question

The weight of the limb is W=15 lbs.The contact of foot with the ground can be modeled as a pin/hinge here. Determine the reaction force of the ground and the reaction at the knee joint and its direction/angle θ. Note: use the thee force member condition to find the angle of FK.Q4.As it’s been shown in the below figure,a person is using an exercise machine. Points A and B correspond to the shoulder and elbow joints, respectively. Relative to the person, the upper arm (AB) is extended toward the left (x-direction) and the lower arm (BC) is extended forward (z-direction). At this instant, the person is holding a handle that is connected by a cable to a suspending weight. The weight applies an upward (in the y-direction) force with magnitude F on the arm at point C. The lengths of the upper arm and lower arm are AB̅̅̅̅= 20cm and BC̅̅̅̅= 25cm, respectively, and the magnitude of the applied force is F = 400 N.Determine the components of reaction developed at the shoulder joint A When the system is in equilibrium. Consider the shoulder joint as fixed in this condition and neglect the weights of the upper and lower arms.
