Homework Statement
A steel pipe..has a diameter of 116mm...length of 1.8m...and wall thickness of 8mm...gets pounded down by an axial compressive load of 180kN... Let's say that E (the elasticity) = 200GPa...and V(the poisson's ratio) is 0.3... i need to work out the CHANGE IN WALL THICKNESS ...how?? anyone??
Homework Equations
change in diameter = -0.3 x (change in length / initial length) x initial diameter
change in length = (bob x initial length) x E
bob = Force / Area (CSA)
CSA = Pi x radius squared
The Attempt at a Solution
I don't know where to go from here..HELP!
