Detailed explanation-1: -The strain produced in rubber is much larger compared to that in steel. This means that steel has a larger value of Young’s modulus of elasticity and hence, steel has more elasticity than rubber.
Detailed explanation-2: -By this deflation, steel is more elastic than rubber because steel comes back to its original shape faster than rubber when the deforming forces are removed.
Detailed explanation-3: -Answer and Explanation: Steel is more elastic than rubber because the strain in the steel in steel is much smaller than the rubber. Since the young modulus of elasticity in steel is higher than the rubber.
Detailed explanation-4: -The modulus of elasticity of steel is greater than that of rubber under the same stress because, the modulus of elasticity is inversely proportional to strain.
