A motor drives two loads. One has rotational motion. It is coupled to the motor through a reduction gear with a = 0.1 and efficiency of 90%. The loads have a moment of inertia of 10kg-m^2 and a torque of 10N-m. The other load has translational motion and consist of 1000kg weight to be lifted up at a uniform speed of 1.5m/s. Coupling between this load and the motor has an efficiency of 85%. The motor has an inertia of 0.2kg-m^2 and runs at a constant speed of 1420 rpm. Determine the equivalent inertia referred to the motor shaft and power developed by the motor.

A motor drives two loads. One has rotational motion. It is coupled to the motor through a reduction
gear with a = 0.1 and efficiency of 90%. The loads have a moment of inertia of 10kg-m^2 and a torque of
10N-m. The other load has translational motion and consist of 1000kg weight to be lifted up at a
uniform speed of 1.5m/s. Coupling between this load and the motor has an efficiency of 85%. The motor
has an inertia of 0.2kg-m^2 and runs at a constant speed of 1420 rpm. Determine the equivalent inertia
referred to the motor shaft and power developed by the motor.
