How do you estimate the required compressed air pressure to move a cylinder with a given load?

• A. F divided by piston area
• B. F multiplied by piston area
• C. Pressure added to area
• D. Area divided by force

Answer: (B)

The key idea is that pressure, force, and piston area are related by F = P × A. This means the pressure you need to move a given load on a cylinder is found by rearranging the equation to P = F / A. So to estimate the required compressed air pressure, divide the load (the force you must overcome) by the piston area. For example, a 500 N load on a piston with an area of 0.01 m² requires about 50,000 Pa (roughly 0.5 bar). In real systems you’d also account for friction, seal losses, back pressure, and a safety factor.
