प्रश्न
Read the following statements below carefully and state, with reasons, if it is true or false
The Young’s modulus of rubber is greater than that of steel;
Advertisements
उत्तर
False
For a given stress, the strain in rubber is more than it is in steel.
Young’s modulus, Y = Stress/Strain
For a constant stress: `Y prop 1/Strain`
Hence, Young’s modulus for rubber is less than it is for steel.
