My question is a bout this question below (Bear with me people)

A tie bar 25mm in diameter and 1m long extends in length by 1.2mm, when subjected to an axial tensile force of 80KN. If the diameter decreases by 0.007mm, determine the values of poisson's ration, and E,G and K.

My question is how do you solve the Poissions ratio if it is equal to lateral strain divided by Axial strain. Can someone help me to determine the lateral strain and do I need to covert 80KN into strain.

How can I figure out lateral strain that what I really need to know?
