Kelly is holding their leg out at an angle of 45 degrees to the horizontal, with a 75 N weight (assume the force vector is aligned with the long edge of this page) strapped at her ankle. A figure of the example is provided. The leg length is 50 cm, and the horizontal distance from the 75 N weight to the knee. joint is 35.4 cm. You will not include the weight of the leg and foot segment for your calculation in this example. A. Draw a free body diagram of the leg and foot segment. While your mathematical answer does not require the weight of the leg and foot, make sure to still draw its approximate location on the diagram (5 points) B. What is the muscle torque required to hold the leg in this position? Please keep the answer with Newtons and centimeters. Include your response to one decimal place. You will not include the weight of the leg and foot segment for your calculation in this example. (10 points) C. What is the anatomical direction of this torque? (2 points) D. Fill in the blank: In the provided diagram, you are viewing the person's leg in the anatomical plane. (2 points) E. Would the torque about the knee joint increase, decrease, or remain the same in each of these examples? Assume that each change is being done one at a time. Justify your answer for full points. (2 points each = 6 points) 35.4 cm 50 cm
