A 175.0 g uniform meter stick used as a balance has masses 325.0 g at the 90.0 cm position and 200.0 g at the 25.0 cm position. Where should the meter stick be pivoted so the system is balanced?

Forces of 56 N and 52 N are applied at the ends of a meter stick and a force of 65 N is applied at its center as shown. Determine the magnitude of the torque on the meter stick due to these forces about the point P. 2325 E4Q11.png
