The knee is stationary in a neutral position The joint angle between thigh and leg is 0 = 90. The resistive forces are the weights of the leg and the foot. The distance between the axis of rotation of the knee joint and the center of mass of the leg is dLEG = 20.5 cm, the distance to the center of mass of the foot is dFT = 47 cm. The insertion point of the hamstring is a distance dHAM = 2.5 cm away from the knee joint axis. The angle of attachment for the hamstring muscle is = 101. The mass of the foot is mFT = 1.3 kg, the mass of the leg is MLEG = 3.8 kg. a) What is the total magnitude of gravitational torque due to the weights of the LEG and FOOT? (2 pts.) b) What is the magnitude of FHAM to maintain this position? (3 pts.) Hip FHAM 8 Ankle HAM dLEG dFT Fwt,LEG Fwt, FT
