Concept

Problem: A uniform bar has mass 3.00 kg and length 6.00 m. The lower end of the bar is attached to the wall by a frictionless hinge. The bar is held stationary at an angle of 53.1° above the horizontal by a horizontal cable that runs from the upper end of the bar to the wall. For an axis at the hinge, what is the magnitude of the torque produced by the weight of the bar?
