Engineering Materials MCQ with Answers

46) The ratio of direct stress to volumetric strain in case of a body subjected to three mutually perpendicular stresses of equal intensity, is equal to

Answer is:

bulk modulus

Explanation:

When a body is subjected to three mutually perpendicular stresses, of equal intensity, the ratio of direct stress to the corresponding volumetric strain is known as bulk modulus. Bulk Modulus is usually denoted by K.

47) The stress at which extension of the material takes place more quickly as compared to the increase in load is called

Answer is:

yielding point of the material

48) Which of the following attributes explain why pure metals are not frequently used in engineering applications

Answer is:

Softness

49) Flow stress corresponds to

Answer is:

plastic deformation of solids

50) When it is indicated that a member is elastic, it means that when force is applied, it will
