III. Torque and angular acceleration The rigid bar shown at right is free to rotate about a fixed pivot through its center. The axis of rotation of the bar is perpendicular to the plane of the paper. ban aninn \F\ = F, M A. A force of magnitude F, is applied to point M as shown. The force is always at a right angle to the bar. For each of the following cases, determine whether the angular acceleration would be in a clockwise or counterclockwise sense. es oonstaib orth • The bar was initially at rest. (Hint: Consider A@.) • The bar was spinning at a constant rate before the force was applied. Does your answer for the angular acceleration depend on whether the bar was originally spinning clockwise or counterclockwise? Explain.
