Why doesn't out body get crushed due to atmospheric pressure around us?
The atmospheric pressure will not crush us because there is a balanced force around us. The contents of our bodies are pushing out as much as the air is pushing in. In fact, it used to be thought that you would explode if you were exposed to a vacuum, though this is now thought to be wrong (It would be awful, but your skin is very stretchy). You can work out the pressure with the equation: PRESSURE= FORCE x AREA.
