Hello friends welcome in mechanical engineering mcq website. In this mechanical engineering lecture today we solveing the strength of materials (som) subject multiple choice questions Young's modulus mcq - Strength of materials (objectives questions).

Multiple choice questions (Mcq) on Young modulus of elasticity (modulus of elasticity)

MCQ - 1

The young modulus of elasticity (modulus of elasticity) is define as a ratio of .........

A) linear stress to linear strain

B) Shear stress to shear strain

C) normal strain to normal stress

D) pressure to cross section area

Answer - A

MCQ - 2

Modulus of elasticity value is a .......... for all materials

A) Same

B) Different

C) Both A and B

D) Can't say

Answer - B

MCQ - 3

Modulus of elasticity is

A) linear strain / linear stress

B) linear stress / linear strain

C) Lateral strain / linear strain

D) shear stress / shear strain

Answer - B

MCQ - 4

The ratio of tensile stress and tensile strain or compressive stress and compressive strain is termed as

A) modulus of elasticity

B) modulus of rigidity

C) Bulk modulus

D) Poission's ratio

Answer - A

MCQ - 5

which modulus of elasticity si unit is

A) Newton

B) Newton / meter

C) Newton / meter²

D) Newton / meter³

Answer - C

MCQ - 6

Young modulus of elasticity unit is same as stress.

A) True

B) False

Answer - A

Solution

In young modulus of elasticity (modulus of elasticity) is defined as ration of normal stress to normal strain, strain has no unit so young modulus of elasticity unit is N/m² and this is same as stress.

MCQ - 7

modulus of elasticity (young modulus) is represented by

A) A

B) E

C) G

D) e

Answer - B

MCQ - 8

In The ratio of linear stress to linear strain is called as .........

A) modulus of elasticity

B) modulus of rigidity

C) Bulk modulus

D) Poission's ratio

Answer - A

Solution

The ration of linear stress to linear strain is called as modulus of elasticity (young's modulus).

Today we solveing the strength of materials (som) subject multiple choice questions Young's modulus mcq - Strength of materials (objectives questions).

If you have any queri about young's modulus then comment
