Forces & Pressure


So, today I learnt that P=F/A. For something with a flat surface, it is easy to grab. Then came to my mind, how about the pressure exerted by a curved surface? How do you calculate the pressure? To make it easier I'll make 2 example questions.



a)Calculate the pressure exerted by a 10kg cylinder with a radius of 5m and a height of 10m on a flat surface.(g=10ms^-1)


b)Calculate the pressure exerted by a 10kg sphere with a radius of 5m on a flat surface. (g=10ms^-1)
