What do you mean by elastic hysteresis?
Advertisements
उत्तर
In case of some materials like vulcanized rubber, when the stress applied on a body decreases to zero, the strain does not return to zero immediately. The strain lags behind the stress. This lagging of strain behind the stress is called elastic hysteresis.

Draw a labelled graph of tensile stress against tensile strain for a metal wire up to the breaking point. In this graph show the region in which Hooke’s law is obeyed.
The stress-strain graphs for two materials are shown in figure (assume same scale).
 Material (i) |
 Material (i) |
- Material (ii) is more elastic than material (i) and hence material (ii) is more brittle.
- Material (i) and (ii) have the same elasticity and the same brittleness.
- Material (ii) is elastic over a larger region of strain as compared to (i).
- Material (ii) is more brittle than material (i).
