input piston with an area of 1⁄4 in2 and an output piston with an area of 15 in2. An input force of 50 lb is applied, and the input piston moves 30 inches. What is the pressure ... output piston move, and what is the mechanical advantage? Pressure = Force ÷ Area = 50 ÷ 1⁄4 = 200 psi Force = Pressure × Area = 200 × 15 = 3,000 lb Mechanical Advantage = Force Out ÷ Force In Figure 5-42. Force, area, pressure relationship. Figure…
