Question:

A bicycle tire pump has a piston with area $0.40 \, in^2$. If a person exerts a force of $23 \, lb$ on the piston while inflating a tire, what pressure does this produce on the air in the pump?

Solution:

By the definition of the pressure, we get:

$$P = \frac{F}{A} = \frac{23 \, lb}{0.40 \, in^2} = 57.5 \, Psi.$$

Answer:

$$P = 57.5 \, Psi.$$
