Important Questions on Elastic Behaviour of Solids
The quality of the material which opposes the change in shape, volume, or length is called

A sagging roof is totally undesirable in a building hence, the material used for this purpose must have a large plastic region in its stress-strain curve.

Resistance to elastic deformation of a material is measured by:

How the strengths of the two materials can be compared?

Perfectly plastic body is an ideal concept.

Define a Perfectly plastic body.

The elastic behaviour of a body can be turned into plastic behaviour under the larger deforming force.

What do you understand by the plastic deformation of a body?

What is Plasticity?

As compared to concrete, steel has compressive strength:

In a technical sense a substance with a _____ elasticity is one that requires a large force to produce a distortion-for example, a steel sphere.

Out of the following whose elasticity is independent of temperature;

If you try to displace any ball from its equilibrium position, the spring system tries to restore the ball back to its original position.

The temperature of a wire is times . The Young’s modulus of elasticity.

Which of the following statement is incorrect?

Discuss Elasticity and Plasticity in solids with example.

A wire is suspended vertically from a rigid support. When loaded with a body in air, the wire extends by and when the body is immersed completely in water, the extension is reduced to . The relative density of material of the body is

For a given material, the Young’s modulus is times that of the modulus of rigidity. Its Poisson’s ratio is:

For an ideal liquid, bulk modulus is infinite and shear modulus is zero.

Distinguish between elasticity and plasticity.
