Question

what are fluids? what is the difference in the effect of shear stress on solids and fluids ?

Answer 1

Explanation:

In physics, a fluid is a substance that continually deforms under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them.

Answer 2

Answer:

fluids are substances which can flow . for example: liquids and gases. i think so shear stress on solids can cause next to no effects, since solids are not compressible. But fluids are compressible so fluids can be compressed on shear stress.. Solids may or may not be compressible.( for example: sponge and rubber are compressible)
