Question

The atmospheric pressure at sea level is 1.013 x 105 N/m2. The unit of pressure N/m2 is also called a pascal (Pa). The surface area of an average adult body is about 2 m2. How much crushing force does the atmosphere exert on people? Why don't we get crushed?

Answer 1

Crushing force will be
`2.026* 10^5N`

Step-by-step explanation:

We have given that atmospheric pressure
`P=1.013* 10^5N/m^2`

Area is given as
`A=2m^2`

We have to find the force

We know that force is given by

`Force=pressure* area=1.013* 10^5* 2=2.026* 10^5N`

The reason that we do not get crushed is because the force is distributed over our bodies, and because we have air inside our bodies pushing outwards (the air in your blood,lungs, etc.). The pressure inside of our bodies keeps the air outside from crushing it.
