Our atmosphere exerts a pressure of 14.7 lb/in2. What is the force on one square foot of the earth’s surface caused by the atmosphere

The force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.

Explanation:

To force is given by:

  (1)

Where:

P: is the pressure = 14.7 lb/in²

A: is the area = 1 m²

By entering the above values into equation (1) we have:

Therefore, the force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.

I hope it helps you!

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
