Question

Which of the following factors affect the mechanical properties of a material under applied loads?

(a) Content of alloys

(b) Grain size

(c) Imperfection and defects

(d) Shape of material

This question was posed to me by my college director while I was bunking the class.

This is a very interesting question from Mechanical Properties topic in division Properties of Engineering Materials of Engineering Material & Metallurgy

Answer 1

Correct answer is (d) Shape of material

For explanation: Contents of alloys improve or decrease the hardness and strength of materials. Finer grain sizes improve the strength of the material. Imperfection and defects reduce the strength of the material. Shape, however, has little or no effect on the material.
