I am trying to work out the compressive stress in a material.
I have a strut diameter of 30mm. Length is 2.5m. Load 0f 30kN. Modulus of elasticity for the material is 160GPa.
I need to find the amount it compresses by.
I have came up with the answer: 1.130973355x10^10m
By using Stress/Strain.
I am stuck on the 160GPa. I have wrote it in the equation as: 160x10^9.
But not sure if this is correct. And it should just be 160.
And not sure if I have calculated it correctly.
Can anyone help or give advice?
