1 of 2 hanics ment #6 - Inverse Dynamics Name During the push off phase of running, an athlete experiences the following ground reaction forces: GRFx = 456N, GRFy=847N. These forces are oriented 10cm below and 5cm in front of the center of mass of the foot. At this instant, the ankle joint center is 9cm above and 6cm behind the center of mass of the foot Also at this point in time, the foot has the following accelerations: ax=1.5m/s?, ay m/s. 15rad/sec The mass of the foot is 1kg, and the moment of inertia of the foot is 0.02kgm Calculate Rx, Ry, and the net muscle torque acting about the ankle joint at this instant. Foot At this point, the ankle joint center is 20cm below and 12cm behind the center of mass of the shark The knee joint center is 19cm above and som in front of the center of mass of the shark Also at this point in time, the shank has the following accelerations: ax=2mis ay=Om/s. --Bradsec The mass of the shank is skg, and the moment of inertia of the shank is 0.2kgm Calculate Rx, Ry, and the net muscle torque acting about the knee joint at this instant. Shank (lower leg)
