Homework Statement
Basically I need to find the pressure on a solid sphere of brass 10,000 feet below the ocean. diameter of the sphere is 11 inches.
Homework Equations
62.4 lb/ft3 p=F/A
The Attempt at a Solution
This is part of a larger problem where I need to find the change in diameter, the change in volume and the strain energy, but first I need to determine the uniform stress compressing the ball.
I figured if I took the column of water above the sphere using 62.4(10,000) then subtracted the excess at the largest cross section of the sphereIE. 62.4(10,000)-(1ftx1ft)-pi(5.5in)^2. If I am right this should give me the weight of the water directly above the sphere. I can then use this weight and divide by the surface area over the entire sphere to get the stress. I have tried variations of this but to no avail.
Ideas? Thank you
