Aman who weights 90 kg (882 n, or -198 lb) is lying on a bed in cervical traction with a weight of 5 kg (49 n, or -12 lb) suspended from a horizontal rope. assuming that the entire body is a single unsegmented object and that the body is in equilibrium, identify all the forces acting on the body (assuming that mu_s for skin on bed is 0.25). the man in question 17 is no longer in cervical traction. a nurse standing at the foot of his bed has grasped his right foot and is pulling him down toward the foot of the bed. again treating the man as a single unsegmented object, determine the minimum force that the nurse must have applied to the man to initiate the movement. assuming now that the leg-foot segment of the man in question 18 is joined to the rest of his unsegmented body by capsuloligamentous structures at his knee, what must be the magnitude of tension in the knee joint capsuloligamentous structures just as the man begins to be pulled toward the foot of the bed? what are the names of the forces causing tension in the capsuloligamentous structures?
