Why Steel is more elastic than Rubber?

By Mandeep Kumar|Updated : July 19th, 2022

Young's modulus for steel is more than that for rubber hence steel is more elastic than rubber. Young's modulus is the ratio between stress and strain. The slope of the linear part of the stress-strain curve for material under tension or compression is represented by Young's modulus.

Answer: The steel is more elastic than rubber because Young's modulus for steel is more than that for rubber.

Young's modulus is also known as the modulus of elasticity and is represented by E. It measures the tension or compression of solid material when the force is applied. The higher value of Young's modulus shows the greater stiffness of a material. The concept of Young's modulus was developed by Leonhard Euler in 1727. However, it was named after British scientist Thomas Young in the 19th century. Young's modulus is used for determining the deflection that will occur in a beam, change in the dimension of a bar made of an isotropic elastic material, etc.

Summary:

Why Steel is more elastic than Rubber?

Young's modulus i.e. the ratio between stress and strain is more than that of rubber hence steel is more elastic than rubber. They are expressed in gigapascals (Gpa).
