The large quadriceps muscle in the upper leg terminates at its lower end in a tendon attached to the upper end of the tibia (see Figure a). The forces on the lower leg when the leg is extended are modeled as in Figure b, where T is the force of tension in the tendon, w is the force of gravity acting on the lower leg, and F is the force of gravity acting on the foot. Find T when the tendon is at an angle of 25.0 with the tibia, assuming that w = 29.0 N, F = 14.2 N, and the leg is extended at an angle 0 of 40.0 with the vertical. Assume that the center of gravity of the lower leg is at its center and that the tendon attaches to the lower leg at a point one-fifth of the way down the leg. (Give the magnitude.) Quadriceps Tendon Tibia a 25.00 T b 174.53 X Your response differs from the correct answer by more than 10%. Double check your calculations. N
