performing extension/flexion movements of the lower leg
about the knee joint (point O) to investigate the forces and
torques produced by muscles crossing the knee joint. The
setup of the experiment is described in Example
above.
The geometric parameters of the model under investigation,
some of the forces acting on the lower leg and its free-body
diagrams are shown in Figs. and For this system, the
angular displacement, angular velocity, and angular accelera-
tion of the lower leg were computed using data obtained
during the experiment such that at an instant when 0 = 65°,

tem assume that a = 4.0 cm, b = 23 cm, ß = 25°, and the net
torque generated about the knee joint is M₁ = 55 Nm. If the
torque generated about the knee joint by the weight of the lower
