Problem
1. A hydraulic lift has a maximum fluid pressure of 500 kPa. What should the piston/cylinder diameter be in order to lift a mass of 850 kg?
2. A laboratory room has a vacuum of 0.1 kPa. What net force does that put on the door of size 2 m by 1 m?
3. A vertical hydraulic cylinder has a 125-mmdiameter piston with hydraulic fluid inside the cylinder and an ambient pressure of 1 bar. Assuming standard gravity, find the piston mass that will create an inside pressure of 1500 kPa.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
