Question

A fluid in equilibrium can't sustain

• A. tensile stress
• B. compressive stress
• C. shear stress
• D. bending stress

Answer 1

Answer:

C. shear stress

A fluid in equilibrium cannot sustain shear stress as it moves and deforms continuously when subjected to it. Therefore, a fluid at rest must be in a state of zero shear stress. This is because a solid can resist shear stress by static deformation, which is not possible for a fluid.
