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 Strain mcq - Strength of materials (objectives questions).

Multiple choice questions (Mcq) on strain (objective questions)

MCQ - 1

The deformation per unit length is called as

A) Strain

B) Shear stress

C) Tensile stress

D) compressive stress

Answer - A

MCQ - 2

The unit of strain is

A) mm

B) N

C) N / m

D) Unit less quanity

Answer - D

MCQ - 3

Strain is ratio of

A) Original length / Change in length

B) Change in length / Original length

C) Force / cross section Area

D) shear stress / shear strain

Answer - B

MCQ - 4

Strain is represent by

A) E

B) e

C) K

D) a

Answer - B

MCQ - 5

Strain is equal to

A) l × dl

B) dl / l

C) l / dl

D) N / m

Answer - B

MCQ - 6

Stress and strain si unit is same

A) True

B) False

Answer - B

Solution

Stress is ratio force per unit cross section area so si unit of stress is N /m² and strain is unit less quanity so stress and strain unit is not same.

MCQ - 7

The ratio of increased in length to original length is called as .........

A) Stess

B) modulus of rigidity

C) Compressive strain

D) Tensile strain

Answer - D

Solution

The ration of increased in length per unit original length is called as tensile strain

MCQ - 7

The ratio of decreased in length to original length is called as .........

A) Stess

B) modulus of rigidity

C) Compressive strain

D) Tensile strain

Answer - C

Solution

The ration of increased in length per unit original length is called as linear strain

Today we solveing the strength of materials (som) subject multiple choice questions Strain mcq - Strength of materials (objectives questions).

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