//Strength Of Material By G.H.Ryder
//Chapter 4
//Example 2
//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
GdashByG=1+errorG;
//G*(1+nu)=Gdash*(1+nudash)
errornu=-errorG*(1+nu)*100/nu; //approxiamate percentage error in Poission's ratio
//Alternative Method
//E=2*G*(1+nu)
//Since deltaE=0 as E does not vary
//0=2*deltaG*(1+nu)+2*G*deltanu
deltaGbyG=1/100; //percentage error in G
deltanu=deltaGbyG*(1+nu); //Absolute error in Poission's Ratio
errornu=-deltanu*100/nu; //percentage error in Poission's Ratio
printf("Error in Calculation in Poissions Ratio is about %.f percent",errornu)
