Rubber is an elastic material derived from natural sources like latex or synthesized artificially. It has high flexibility and can stretch significantly before returning to its original shape. Rubber is used in a variety of applications such as tires footwear seals and in industries requiring elasticity and durability.

Class 11 Physics Chapter 8 covers the mechanical properties of solids. It explains concepts such as stress strain Hooke’s law elasticity plasticity Young’s modulus bulk modulus and shear modulus. The chapter discusses how solids deform under stress how they respond to stretching compressing and bending forces and the factors affecting their mechanical behavior in different conditions.

    1. When a rubber is stretched in length, it experiences a deformation in which the material attempts to preserve its volume. Since the length increases, the cross-sectional area reduces, bringing down the thickness. In most cases, width can increase as rubber stretches in length to preserve the overall volume.
