PhysCasts: Torque on a Hinged Rod
Rowlands, W. (Wayne) (2013)
In this problem we will look at calculating the torque on an object about an axis. A uniform rod of 1.5 m and mass 0.80 kg is attached at one end to a hinge on a vertical wall. The rod makes an angle of 60 degrees above the horizontal. What is the magnitude of the torque about the hinge from the rod's weight?
