Question

Select the correct statement:
(i) In solids, if we apply shear stress, deformation occurs, but does not increase with time.
(ii) In liquids on application of shear stress, deformation increases with time.

• A. (i) only
• B. (ii) only
• C. (i) and (ii)
• D. None of these

Answer 1

The correct option is C (i) and (ii)


As we know, in solids on application of shear stress, deformation occurs but does not increase with time.
While in fluids, under same conditions, deformation occurs but increases with time.
A fluid can not sustain shear stress when at rest.
