Homework Statement
A 75 kg solid cylinder, 2.1 m long and has an end radius of 5.0 cm, stands on one end. How much pressure does it exert?
Homework Equations
P = f/a
P= pwh (this is the equation my teacher gave us on a power point but I might just be using it wrong)
v = pi r2h[/B]
The Attempt at a Solution
v = .052 pi 2.1
v = .016 m3
density = 75 / .016
density = 4687.5[/B]
weight = 75 x 9.8
weight - 735
P = 735 x 4687.5 x 9.8
P = 33764062.5
I feel like that number is way to big and I am doing more work than is needed. Thanks in advance!
