Textbook Question
Chapter 5, Problem 14SP
A horizontal essentially weightless lever is pivoted so it can rotate freely in a vertical plane. A downward force of 30.0 N is applied perpendicularly to the lever at a point 25.0 cm from and to the right of the pivot. Determine the torque on the lever, about the pivot. [Hint: Draw a diagram and specify the direction of the torque.]
