For the compressor mechanism described in Problem, determine the torque required from the motor if the motor is rotating at 800 rpm and accelerating at a rate of 5000 rad/s2.

The compressor mechanism shown in Figure is driven clockwise by a DC electric motor at a constant rate of 800 rpm. In the position shown, the cylinder pressure is 70 psi, and the piston weighs 0.75 lb. The coefficient of friction between the piston and the compressor cylinder is 0.1. The weight of all other links is negligible. At the instant shown, determine the torque required from the motor to operate the compressor.
