(b) Elastic limit

(c) Ultimate strength

(d) Plastic limit

I had been asked this question by my school teacher while I was bunking the class.

This interesting question is from Shear Stress and Pressure Gradient in division Viscous Flow & Turbulent Flow of Fluid Mechanics

Answer 1

Correct answer is (b) Elastic limit

For explanation: Hooke’s law states that force is directly proportional to its extension. Hooke’s law is applicable within the elastic limit, when the body is deformed. Example: plucking the strings of a guitar.
