Problem
1. Two hydraulic cylinders maintain a pressure of 175 psia. One has a cross-sectional area of0.1 ft2, the other 0.3 ft2. To deliver a work of 1 Btu to the piston, how large a displacement (V) and piston motion (H) are needed for each cylinder? Neglect Patm.
2. A linear spring, F = ks(x - x0), with spring constant ks = 35 lbf/ft, is stretched until it is 2.5 in. longer. Find the required force and work input.
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.
