Question

Consider a ladder leaning against a wall and pick the axis of rotation to pass through the point where the bottom of the ladder touches the ground The weight of the ladder exerts a torque about this axis. What other forces on the ladder will also exert a torque about this same axis? The forces of friction on the ground. The forces of friction with the wall. The normal force on the bottom of the ladder. The normal force on the top of the ladder where it touches the wall. Both b and d. Both a and c. All of these forces.

Explanation / Answer

(e) b and d acts torques because torque = force* distance and distance is zero in the other cases
