Question 1:

The graph shown below shows qualitatively the relation between the stress and the strain as the deformation gradually increases. Within Hooke’s limit for a certain region stress and strain relation is linear. Beyond that up to a certain value of strain the body is still elastic and if deforming forces are removed the body recovers its original shape.

1. If deforming forces are removed up to which point the curve will be retraced?

(a) upto OA only

(b) upto OB

(d) Never retraced its path

2. In the above question, during loading and unloading the force exerted by the material are conservative up to

(a) OA only

(b) OB only

(d) OD only

3. During unloading beyond B, say C, the length at zero stress in now equal to

(a) less than original length

(b) greater than original length

(d) can’t be predicted

4. The breaking stress for a wire of unit cross-section is called

(a) yield point

(b) elastic fatigue

(d) Young’s modulus

5. Substances which can be stretched to cause large strains are called

(a) isomers

(b) plastomers

(d) polymers

Answer:
1. (b)
2. (b) : Point B is the elastic limit
3. (b) : Beyond B even if deforming forces are removed still some deformation is left.
4. (c) : The breaking stress for a wire of unit cross-section is called tensile strength.
5. (c) : Substances which can be stretched to cause large strains are called elastomers.
