The simplest model of human standing is called the inverted pendulum model, (as shown in the figure). The sphere with x mark is the center of gravity of the body. A small forward tilt will require the ankle muscle to counter balance the torque produced by the force of gravity. Calculate the torque (in Nm) needed at the ankle to balance the body, if a 60-kg person tilts forward by 20 degrees, and the distance from the center of gravity to the ankle is h 1.3 m.
