369680 Two different types of rubber are found to have the stress-strain curves as shown. Then

369681 Assertion :
Soft steel can be made red hot by continued hammering on it, but hard steel cannot.
Reason :
Energy transfer in case of soft is large as in hard steel.

369682 Assertion :
When an elastic body is subjected repeatedly to the action of alternating deforming forces, its behaviour corresponds to that of less elastic bodies.
Reason :
Elastic fatigue is the property of an elastic body by virtue of which its behaviour becomes less elastic under the action of repeated alternating deforming forces.

369683 Assertion :
The bridges are declared unsafe after a long use.
Reason :
Elastic strength of bridges loses with time.

369684 The diagram shows a force - extension graph for a rubber band. Consider the following staments
