The stress versus strain graphs for wires of two materials A and B are as shown. If and are the Young's moduli of the materials, then:
1
2
3
4
Official Solution
Correct Option:
(3)
Concept:
Hence, slope of stress vs strain graph:
So, slope is inversely proportional to Young’s modulus. Step 1:From the graph:}
•Line A makes
•Line B makes Step 2:Slopes:}
Step 3:Ratio of slopes:}
Step 4:Using inverse relation:}
