Which material will follow the below stress-strain curve?
Correct answer: D. Glass
- A. Copper
- B. Iron
- C. Lead
- D. Glass
Explanation
A stress-strain curve is a graphical way to show the reaction of a material when a load is applied. It shows a comparison between stress and strain.Brittle materials, which comprise cast iron, glass, and stone, are characterized by the fact that rupture occurs without any noticeable prior change in the rate of elongation. Thus, for brittle materials, there is no difference between the ultimate strength and the breaking strength.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
