Answer to Question #158584 in Classical Mechanics for Viccy

Question

Can you explain fluid.

Answer 1

A fluid is a substance that continually deforms (flows) 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.
