2) (120 pts) After successfully landing on the planet Mars, some scientists want to experimentally test the compressor mechanism given below. The compressor mechanism shown below is driven clockwise by a DC electric motor at a constant rate of 800 rpm, and accelerating at 1000 rad/s'. In the position shown, the cylinder pressure is 70 psi, and the plston weighs 2 lb. The coefficient of friction between the piston and the compressor cylinder is 0.5. The weight of all other...
