** A cylindrical bar with a sphere firmly attached to one end is originally at rest in a horizontal position. The bar is pivoted about
a free hinge at one end (Figure 8-61). The bar is 4.00 m long and has a mass of 231 kg. The sphere has a radius of 60.0 cm and a
mass of 53.0 kg. A variable torque is applied to lift the bar by rotating it 37.0° about the pivot at a constant angular speed. Calculate
the work done by the variable torque.
