A bicycle tire pump has a piston with area 0.43 In2. If a person exerts a force of 16 lb on the piston while Inflating a tire, what pressure does this produce on the air in the pump?

Answer:

The pressure produced on the air in the pump is 37.209 pounds per square inch.

Step-by-step explanation:

By definition, the pressure is the force exerted on the piston divided by its area. Given that, force is distributed uniformly on the piston area, the formula to determine the pressure is:


p = (F)/(A)

Where:


p - Pressure, measured in pounds per square inch.


F - Force exerted on the piston, measured in pounds.


A - Piston area, measured in square inches.

If
F = 16\,lb and
A = 0.43\,in^(2), the pressure produced on the air in the pump is:


p = (16\,lb)/(0.43\,in^(2))


p = 37.209\,psi

The pressure produced on the air in the pump is 37.209 pounds per square inch.
