If a force of 1,020 pounds is exerted on a piston, what is the pressure if the area is 1.2 square inches?

If a force of 1,020 pounds is exerted on a piston, what is the pressure if the area is 1.2 square inches?

• A. 750 PSI
• B. 850 PSI
• C. 1,020 PSI
• D. 1,100 PSI

Answer: (B)

To determine pressure, you need to use the formula: Pressure (P) = Force (F) / Area (A). In this case, you have a force of 1,020 pounds exerted on a piston with an area of 1.2 square inches. Using the formula, you can calculate the pressure as follows: P = 1,020 pounds / 1.2 square inches = 850 PSI. This calculation shows that the pressure exerted by the force on the piston is 850 PSI. Understanding this formula is crucial, as it helps in practical applications where pressure calculations are necessary in various fields, including engineering and aviation. The result emphasizes the direct relationship between force and area in determining pressure; as the area increases with the same force, the pressure decreases, and vice versa.
