Elastic Modulie

Question

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:

Difficult

A

load and increase in length
B

stress and strain
C

Yong's modulus and stress
D

Young's modulus and strain

Solution

$Y = \frac{(\frac{W}{A})}{(\frac{∆ l}{l})} \Rightarrow ∆ l = (\frac{l}{YA}) W$
Given, YA = l So, $\frac{∆ l}{W} = 1$
Also from curve, its slope = tan 45° = 1
So, x and y axes represent W and $∆ l$
