Please write all answers in the space provided. If you need additional space, write on the back sides. Indicate your answer as clearly as possible for each question. Write your name at the top of each page as indicated. _______: (20 points) dynamic analysis and gait. Figure 1 shows a free-body diagram of an idealization of the shank during gait at an angle q to the vertical. For simplicity, the foot has been ignored, and the ground reaction force r is assumed to act at the ankle. Also shown are the resultant force fres and moment. Express the resultant moment mres in terms of the ground reaction force r, the mass of the shank m, the moment of inertia of the shank with respect to its center of gravity. Icg, and the accelerations of the shank (acg and a). Note: all unknowns have been drawn in their assumed positive directions. Typical loads that act on the femoral mid-diaphysis during.
