Question #78043
Physics Mass Density problem! HELP!!?
A box-shaped metal can has dimensions 14 in. by 4 in. by 5 in. high. All of the air inside the can is removed with a vacuum pump. Assuming normal atmospheric pressure outside the can, find the total force (in lb) on one of the 4-by-5 in. sides. (Enter the magnitude.)
______lb

______lb
Expert's answer
The normal atmospheric pressure is
p=14.6959528 lb/(in^2 )
The total force (in lb) on one of the 4-by-5 in. sides is
F=pA=(14.6959528)(4)(5)=294 lb.
p=14.6959528 lb/(in^2 )
The total force (in lb) on one of the 4-by-5 in. sides is
F=pA=(14.6959528)(4)(5)=294 lb.
