A vertical solid steel post of diameter d = 23.1 cm and length L=2.36 m is required to support a load of mass m = 8260 kg. You can ignore the weight of the post. Take free fall acceleration to be g = 9.8 m /s^2
A) What is the stress in the post?
B) What is the strain in the post?
C) What is the change in the post's length when the load is applied.
