An electric motor of total weight 3330 pounds is mounted on a simply supported beam with an overhang as shown below. The unbalance of the motor is equivalent to 10 lb at an eccentricity of 5.0 inches. The motor runs at a speed of 1000 rpm. Assume that damping is 2% of critical. Neglect the weight of the beam.
Determine the maximum total bending moment (static plus dynamic) of the beam under steady-state conditions.
