Question

1.) An object exerts a force of 10 lb on an area of 2 square inches. What is the pressure the
object exerts on the surface?

Answer 1

Answer:

The pressure this object exerts on the surface is 5lb/in² or 5psi.

Explanation:

Pressure is force per unit area.

Mathematically, pressure is given by the formula;

$Pressure = \frac{Force}{Area}$

$P = \frac{F}{A}$

Given the following data;

Force = 10lb

Area = 2in²

Substituting into the equation, we have;

$Pressure = \frac{10}{2}$

Pressure = 5lb/in² or 5psi

Hence, the pressure this object exerts on the surface is 5lb/in² or 5psi.
