Q. Assertion :The materials which have very small range of plastic extension are called brittle materials Reason: If the stress is increased beyond the elastic limit, the material will break

Q. If the material has breaking point lies very close to elastic limit, the material is

Q. Distinguish between elastic and plastic materials.

Q. Consider the following statements and select the correct code.
1. For a given stress, the strain produced in glass is much less than that in rubber.
2. In plastic materials, the force of cohesion are very small.
3. Elastic limit is the smallest stress which results in permanent distortion.

Q. Materials get deformed when force is applied. Some of them regain their status when the applied force is removed. They are termed as elastic. Those of which not regaining are called plastic. There may be delay in the regaining in some materials. They are said to have got elastic aftereffect, since they have gone beyond the elastic limit. Repeated application and removal of force break at any point time and so are avoided.
