1- Write the code according to the data tables on matlab 2- write the similar code for Poisson's ratio i. e 3-write another code to draw a plot of absolute values of lateral strain vs. longitudinal strain.

*Area = w x t = 0.283

*Stress = P/A = 176.7

*Yongs Modulus = 0.11

*Poissons Ratio = 0.2407

also, I attached sample code below
