A 125 pound object needs to be lifted vertically one foot. You have a 2-inch diameter piston actuator with a 12 inch stroke connected to a 50 psi source of pressurized air. The mass is restricted by a set of guide rails, which limit it to vertical motion, and which use roller bearings with a friction coefficient of 0.002. Can the object be lifted? How long will it take?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
