### Strain mcq - Strength of materials (objectives questions).

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

MCQ - 2
The unit of strain is

A) mm
B) N
C) N / m
D) Unit less quanity

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

MCQ - 4
Strain is represent by

A) E
B) e
C) K
D) a

MCQ - 5
Strain is equal to

A) l × dl
B) dl / l
C) l / dl
D) N / m

MCQ - 6
Stress and strain si unit is same

A) True
B) False

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

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

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
