Ok maybe I'm just an idiot today, but I have completely forgotten how to calculate psi... Can someone please help?

Lets say I have a 100lb weight on top of a dowel rod... Lets say the area of the dowel rod is 1 sq inch, would there then be 100psi exerted by the other end of the dowel?

And what about the same 100lb weight but the dowel is 1/2 sq inch? Would that make the pressure exerted 200psi?

Thanks alot!

I was always asked to be quiet in class whenever a problem like this was posed, because I was the smarty pants that would always say "Its more than 100 psi!" The teacher would roll their eyes and say "Why's That?" Then I'd say "That Dowel has to weigh something!!" I wonder why when I went to the next level in school my teachers always breathed a sigh of relief?


Remember your physics.....p=F/A
