The product of Young's modulus of the material of the wire with its cross sectional area is equal to its length. Find the parameters representing x and y axes of the curve as shown:

Options

A. load and increase in length
B. stress and strain
C. Young's modulus and stress
D. Young's modulus and strain

Answer

A

Explanation

`Y=(((W)/(A)))/(((trianglel)/(l)))=trianglel=((l)/(YA))W`
Given, `YA=l` Som `(trianglel)/(W)=1`
also from curve its slope `=tan45^@=1`
So, x and y axes represent `W=andtrianglel`
`(epsi)/(W)=10^-1((m)/(Nm))`,`(epsi)/(W)=(trianglel)/(lW)`
From curve, slope`=tan45^@=1=(l)/(YA)=(trianglel)/(W)`
So, `(epsi)/(W)=10^-1=(1)/(l)((trianglel)/(W))=(1)/(l)`
`l=(1)/(10^-1)=10m=1000cm`
