What is total downward atmospheric force on the top of a 0.21 m by 0.26 m book lying on a table? Why doesn't this force break the table?
If the bottom surface of the book touches the surface of the table perfectly, then the downward atmospheric force on the book = Patm * Surface area of the book.
P atm = 10^5 N/m^2
Area = 0.21*0.26 m^2
Atm force = 10^5 * 0.21*0.26 N = 5460 ...
