Perform a dynamic analysis for a knee extension movement. The knee extensors insert on the tibia at an angle A = 35 and at a distance d = 5.4 cm from the axis of rotation of the knee. The combined weight of lower leg and foot is F, = 49 N. Rotational inertia of the combined lower leg and foot is | = 0.543 kgm?. The joint angle with respect to the right horizontal is 8 = 115. The angular acceleration of lower leg / foot segment has been measured to be a = +16 rad/s2. The horizontal acceleration is computed to be a, = +0.235 m/s?, while the vertical acceleration is a, = + 0.146 m/s2. Compute the following: a) The gravitational torque due to the weight of the leg/foot (T). (2 pts.) b) The underlying knee muscle torque (T,,). (2 pts.) ) The associated muscle force (F,) that gave rise to Ia (2 pts.)
