Question
Pressure cookers have been around for more than 300 years, although the early ones had a nasty habit of exploding. How much force must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 24.0 cm in diameter and the gauge pressure inside is 2.90 atm? Neglect the weight of the lid.N Pressure cookers have been around for more than 300 years, although the early ones had a nasty habit of exploding.

N
Explanation / Answer
P=F/A => F= P*A= P*r2 = 2.90*(3.14*0.24^2) = 0.13 N
