A pressure gauge measures a force of 30 pounds on an area of 1 square inch. What is the pressure in PSI?

To determine the pressure in pounds per square inch (PSI), you can use the basic formula for pressure, which is defined as force divided by area. In this scenario, the gauge measures a force of 30 pounds acting on an area of 1 square inch.

The calculation involves dividing the total force (30 pounds) by the area (1 square inch):

Pressure = Force / Area

Pressure = 30 pounds / 1 square inch = 30 PSI

This result of 30 PSI accurately reflects the pressure exerted as described in the question. The direct relationship between the force applied and the area over which it is applied is fundamental to understanding pressure, making this calculation straightforward and leading to the correct answer.
