Worksheet: The Force Exerted by a Rotating Planar Body on Its Axis of Rotation
In this worksheet, we will practice how to calculate the force that a rotating body with angular speed exerts on the axis of rotation.
A uniform rod of length and mass is free to rotate in a horizontal plane about a vertical axis passing through its center. A horizontal force of constant magnitude is applied to one of the ends of the rod in a direction perpendicular to the rod causing the rod to rotate with an angular acceleration of , where is the acceleration due to gravity. Find the magnitude of the force applied.
