tensile stress
Related Strength of Materials MCQ with Answers
Answer is:
directly
Answer is:
all of these
Explanation:
The thermal or temperature stress is a function of
* increase in temperature
* modulus of elasticity
* coefficient of linear expansion
Answer is:
Stress is directly proportional to strain within elastic limit.
Answer is:
linear strain
Explanation:
The deformation of the bar, per unit length in the direction of the force (i.e. δl/l) is known as primary strain or linear strain.
When a change in length takes place, the strain is known as linear strain.
The deformation of the bar per unit length in the direction of the force is known as linear strain.
