Which is more elastic- steel or rubber?


Steel is more elastic than rubber. Elasticity is measured by how much time a body takes to come back to it's original state after being deformed.

The Young's modulus of steel is greater than rubber.

Graphite consists of planes of carbon atom, which are held by weak forces. What expectations can you make about its rigidity?

The value of modulus of rigidity of the graphite will be small because the carbon atoms are held be weak forces.

Why we have to do work in stretching a wire?

When a wire is stretched, the inter-atomic separation increases and inter-atomic forces comes into play. To displace the atoms against interatomic forces, we need to do work to deform the spring.

 Do elastomers follow Hook's law?

The substances which can be stretched to cause large strains are called elastomers.
Hooke's law states that stress is directly proportional to the strain.
Elastomers violate hook's law.

A wire is cut to half of its original length. How will its Young's modulus change?

Young's modulus is independent of the dimensions of wire but depends on the material of wire. Therefore the Young's modulus of wire remains unchanged.
