what pressure does this produce on the air in the pump?

Question

A bicycle tire pump has a piston with area 0.45 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 1

Need to understand what units for pressure is. Pressure usually uses units "psi" which is lbs/in² also means that it's a force over and area. You have an area and a force so

Pressure=Force/Area

P=16lb/0.45in²

=35.6 psi
