Question

What ensures that a fluid at rest cannot sustain a shear stress?

Options

Choose one · Correct answer highlighted

High viscosity Lack of rigidity Correct Surface tension Compressibility

Explanation

Fluids lack rigidity and cannot resist shear stress without flowing. Any attempt to apply shear stress causes deformation (flow), as fluids have no fixed shape, unlike solids, which resist shear due to strong intermolecular forces.
