Question

Rotational Motion

Recall that in part C of section II of the tutorial Equilibrium of rigid bodies a T-shaped board was hung from the hole through the center of mass and held at an angle as shown. You observed that the board remained at rest when released. What does this observation imply about the net torque about the pivot Explain. Draw an extended free-body diagram for the board in the space at right. Is the point at which you placed the gravitational force on your diagram consistent with your answer for the net torque about the pivot Explain.
