How Do Equilibrium and Elasticity Determine Stress and Strain in a Steel Post?

[eureka360]

hi guys... can you please help me with these problem?
it says... a vertical solid steel post 25 cm in diameter and 2.5 m long is required to support a load of 8000 kg. you can ignore the weight of the post... what is the stress in the post? what is the strain in the post? and what is the length when the load is applied?... what kind of stress is it? a bulk? of tensile? please somebody help me... thanks

You're first going to have to show your thoughts on the problem... you might even need to know some constants relating to the steel... but you need to think about this; I'm not digging in my texts until you do.
