A vertical solid steel post of diameter d = 24cm and length L = 2.10m is required to support a load of mass m = 8200kg. You can ignore the weight of the post. Take free fall acceleration to be g=9.8m/s2.
Part A What is the stress in the post?
Part B What is the strain in the post?
Part C What is the change in the post's length when the load is applied?
