1. A woman performs leg extension exercises using her leg as a free weight. Determine how much force her gluteal musculature generates during knee extension at the indicated hip joint position. Her gluteal musculature inserts on the femur at an angle of =30 and at a distance dgl =0.068 m from the axis of rotation of the hip. The mass of her thigh is estimated to be mthigh =6.45 kg, and the mass of her leg is mshank =2.95 kg. The distance of the CM of the thigh segment to the hip joint axis is estimated to be dthigh =0.136 m, the equivalent distance to the leg is dshank =0.546 m. The distance of the CM of the total leg to the hip joint axis is dCM =0.31 m. The joint angle =47 is the angle between the thigh and to the left horizontal. The total inertia of the leg around the hip joint axis is computed as I =0.979 kgm2. The linear acceleration of the legs CM in the vertical direction is ay =0.22 m/s2 and in the horizontal direction ax =0.25 m/s2. The angular acceleration was measured to be =-7.8 rad/s2(clockwise).
a) What is the magnitude of the total gravitational torque Tgra around the hip due to the weights of the shank and thigh?(3 pts.)
