Ok, so 1 atm≈101,300 Pa that is 101,300 newtons per square meter, presumably at sea level. If we look at the force in terms of lbs this is 101,300 N* (.225 lb/1 N)≈22,792 lb. The pressure per square meter seems pretty intense to me when I thought of it in terms of force. I didn't ask my instructor about this because I didn't notice at first. It's bizarre; how can their be that much force without things being crushed? At first I thought that it might have something to do with pressure being equal in all directions, so that the forces maybe cancel at some particular depth i.e. a net force is 0. However, that would imply that a planet's atmosphere could not be crushing; we might as well be on Venus.
