+//To calculate Percentage error in Poission's ratio
+clc();

+//Initialization of Variables
+errorG=1/100; //Percentage error in determination of G
+nu=0.25  //Correct value of Poission's Ratio
+
+//Computations
+
+//Gdash=(1+errorG)*G

+
+//Alternative Method

+//Since deltaE=0 as E does not vary
+     //0=2*deltaG*(1+nu)+2*G*deltanu
