This video goes over Poisson’s Ratio and how useful it can be when determining the dimensions of a deformed object. It is the ratio between the Lateral Strain and the Longitudinal Strain.

(0:00) Poisson’s Ratio
(2:10) Poisson’s Ratio Equation
(3:07) Problem statement: The rigid beam rests in the horizontal position on two 2014-T6 aluminum cylinders having the unloaded lengths shown. If each cylinder has a diameter of 30mm, determine the placement x of the applied 80 kN load so that the beam remains horizontal. What is the new diameter of cylinder A after the load is applied? Poisson’s Ration = 0.35
