Wednesday, december 15, 12:30 3:30 pm, 1994: write all answers in the space provided. If you need more space, write on the back sides: write your name on the top of each page as indicated. Indicate your answer as clearly as possible for each question: (10 points) forces and moments at joints. Figure 1 depicts a schematic of the proximal femur with the joint contact j and abductor a forces shown, during the single legged stance phase of gait. Show, with your own free-body diagram analysis, why the angle b must always be greater than angle a. Name:_____________________________: (15 points) dynamics of human motion. For the following two cases, draw a free-body diagram showing all loads and accelerations and write out the equation of rotational equilibrium as specified below. In each case, ignore the mass of the foot, model the shank as a uniform bar of length l and mass m, and include all relevant inertial (acceleration) terms.
