The type of business your organization is in will determine the best mechanical engineering interview questions to use.
We discuss some typical interview queries, behavioral interview queries, and technical interview queries in this article so that you can ask a mechanical engineer when you meet them for an interview. Table of Contents.
You can begin the interview by posing a few general engineering interview questions that are connected to mechanical engineering. These will facilitate conversation and help you get to know the candidate.

What are the different kinds of stresses.
There are three different types of stresses: normal, shear, and volumetric.
When a force acts perpendicular to the surface area, normal stress is created.
| Normal stress [σ] = |
|
When a force acts parallel to the surface area, shear stress () results.
| Shear stress [τ] = |
|
Volumetric stress [v] is when a force acts in a way that results in an increase in volume.
The ratio of the changed dimension to the starting dimension is known as strain.
What are the different kinds of strains?
There are three kinds of strains. Linear strain, Shear strain, and Volumetric strain.
Linear strain is defined as the ratio of the changed dimension to the starting dimension.
| Linear strain [ε] = |
|
Shear strain is defined as the ratio of the change in the shear dimension to the original dimension.
| Shear strain [φ] = |
|
Volumetric strain [v] is defined as the proportion of the volume change to the initial volume.
| Volumetric strain [εv] = |

A graph that depicts the relationship between stress and strain for a material is called a stress-strain curve. On the stress-strain graph, which has stress on the X axis and strain on the Y axis, a stress-strain curve is drawn.
According to Hookes law, the force needed to cause a relatively small deformation in an object is directly proportional to the size of the deformation.
The definition of the Poissons ratio [] is the proportion of lateral strain to longitudinal strain.
Formula
| Poissons ratio [ν] = |
|
The longitudinal stress to strain ratio, or Youngs modulus [E], is a measure of an object’s stiffness.
| Youngs modulus [E] = |
|
The ratio of shear stress to shear strain is known as the rigidity modulus [G].
| Rigidity modulus [G] = |

Why did you choose to study mechanical engineering?
With this mechanical interview query, the interviewer can discover the applicant’s preferences for mechanical engineering. It reveals their enthusiasm for the subject and what they find appealing about engineering in general.
Do they seek employment at all, or do they seek to improve society through superior engineering design?
If you have a bachelor’s degree in material science or material engineering, log on to the Wisdom Jobs website. The study of strength of materials, also known as mechanics of materials, examines how solid objects respond to stresses and strains. Many different techniques for calculating the stresses and strains in structural members, such as beams, columns, and shafts, are used in the study of materials’ strength. The strength of a material’s ability to withstand an applied load depends on both theory and experience and is being developed scientifically. Examine the Strength of Materials job interview questions and answers provided to chart your future as a biomedical engineer, project manager, quality manager, material engineer, and environmental engineer.
