1. Tell us what do you enjoy least as Assistant Design Engineer?

Guess what? You need to be honest with this answer too – but be careful not to be too negative – or you might talk yourself out of the job altogether! With this answer, ‘safe' answers might include you hate the fact that sometimes designing particular part may take some time. Sometimes the quality doesn't meet the numbers, these comments that most people in the design industry would agree with- so they may give you common ground with you interviewer.

2. Tell me what is the use of mechanical engineer's scale?

This is flat or triangular shape and used for making drawings of machines and structural parts in 1/8, 1/4, 1/2 or full size.

3. Tell me some methods of reducing stress concentration?

Some of the methods are:

☛ Avoiding sharp corners.
☛ Providing fillets.
☛ Use of multiple holes instead of single hole
☛ Undercutting the shoulder parts.

4. Tell me what do you mean by First Aid?

First Aid is immediate and temporary care given to a person who affected accidental injury or a sudden illness before the arrival of doctor.

5. Tell us the difference between brittle fracture and ductile fracture?

In brittle fracture, crack growth is up to a small depth of the material.

In ductile fracture large amount of plastic deformation is present to a higher depth.

6. Tell me what is principle stress and principle plane?

A plane which has no shear stress is called principle plane the corresponding stress is called principle stress.

7. Tell me what is a Centre line?

Centreline is a thin line in the form long and short dashes. It indicates area of symmetrical parts, circles and path of motion.

8. Tell me what is a Drawing?

It is a graphical representation of a real thing to define and specify the shape and size of a particular object by means of lines.

9. Explain me stress concentration and stress concentration factor?

Stress concentration is the increase in local stresses at points of rapid change in cross section or discontinuities.

Stress concentration factor is the ratio of maximum stress at critical section to the nominal stress

10. Tell me what are the various phases of design process?

The various phases of design process are:

☛ Recognition of need.
☛ Definition of problem
☛ Synthesis
☛ Analysis and optimization
☛ Evaluation
☛ Presentation
