4. A 2" diameter pneumatic piston is used to lift a load of 200 lb. A. What gas pressure is required to accomplish this task? B. What volume of gas at this pressure is required to extend the piston 14"? C. Assume the piston is extended 14" while supporting this 200 lb load. If the temperature drops from 70°F to 60°F while the piston is extended, how far will the piston retract due to the contraction of the gas? D. If the temperature instead remains constant at 70°F, but the load increases to 220 lb, how far will the piston retract? Assume the piston is initially extended to 14". E. What are the implications of your calculations for the operation of pneumatic systems?
