Calculations
1. Calculate and record the sum of the clockwise and counterclockwise torques.

• Are the torques balanced?
Extension
Use a pulley, hanging mass, and a thread to produce an additional upward force at one end of the beam. You may
need to use tape to secure the thread to the beam.) Adjust the positions of the remaining hanging masses and the
Spring Scale to bring the beam back into balance so it is level horizontally.
• Are all the forces balanced, both for translational and rotations motion?
• Diagram your setup and show your calculations on a separate sheet of paper.
