A pressure gauge measures an area of 1 square inch and has a force of 30 pounds. What is the pressure?

To find the pressure exerted by a force acting over a specific area, you can use the formula:

Pressure = Force / Area

Here, the force is given as 30 pounds, and the area is 1 square inch. By substituting these values into the formula, you get:

Pressure = 30 pounds / 1 square inch = 30 PSI

This calculation shows that the pressure is indeed 30 PSI. Understanding this relationship between force, area, and pressure is fundamental in fields such as engineering and physics, as it helps in analyzing the behavior of fluids and gases.

Other choices do not align with the calculated pressure based on the provided force and area. The correct answer clearly reflects a direct and accurate application of the pressure formula.
