Strain vs stress curves for wires . Which is correct?
1
elasticity of P maximum
2
elasticity of Q maximum
3
tensile strength of R maximum
4
None of these
Official Solution
Correct Option: (3)
Concept:
Slope of strain vs stress graph = inverse of Young’s modulus. Step 1: Elasticity
Steeper line more strain less elasticity Step 2: Tensile strength
Maximum extension strongest wire From graph:
Conclusion:
