Stress - strain graph of three different...

Stress - strain graph of three different are as shown. A,B and C are the Young's modulus of the wires. Which of the following statement is correct ?

A

Y of wire a is maximum

B

Y of wire B is maximum

C

Tensile strength of C is maximum

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
D
As strain is plotted on Y axis and stress is plotted along x axis slope of the graph `=1/Y` or `Y=cot theta=(1)/(tan theta)prop(1)/(theta)[theta" is the angle from stress axis "]`
`:.Y_(A)ltY_(B)ltY_(C)`
