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?© BrainMass Inc. brainmass.com October 15, 2018, 4:28 am ad1c9bdddf - https://brainmass.com/physics/newtons-laws/atmospheric-pressure-on-a-book-lying-on-a-table-85637
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 ...
