Question

a large truck tire is inflated to a gauge pressure of 78 psi. the total area of one sidewall of the tire is 1,270 in2. what is the net outward force (in lb) on the sidewall because of the air pressure? (enter the magnitude.)

Answer 1

The net outward force (also known as the air pressure force) on the sidewall of the tire can be calculated using the equation:

Force = Pressure * Area

Where Pressure is the gauge pressure in psi and Area is the total area of one sidewall of the tire in square inches.

So, the net outward force on the sidewall of the tire is:

Force = 78 psi * 1,270 in^2 = 98,460 lb

The magnitude of the net outward force on the sidewall of the tire is 98,460 lb.
