The pressure needed to produce 500 pounds of force on an 8 square inch area is:

• A. 8 psi
• B. 125 psi
• C. 500 psi
• D. 62.5 psi

Answer: (D)

Pressure is the force per unit area. To find the pressure needed for a given force on a specific area, divide the force by the area: 500 pounds ÷ 8 square inches = 62.5 psi. If you used 8 psi, that would correspond to 8 × 8 = 64 pounds of force; 125 psi would give 1000 pounds; 500 psi would give 4000 pounds. So 62.5 psi matches the given 500 pounds over 8 square inches.
