MECHANICAL ENGINEERING INTERVIEW QUESTIONS
1.)What are the advantages of gear drive?
Ans:-In general, gear drive is useful for power transmission between two shafts, which are near to each other (at most at 1m distance). In addition, it has maximum efficiency while transmitting power. It is durable compare to other such as belts chain drives etc. You can change the power to speed ratio.
Advantages:
- It is used to get various speeds in different load conditions.
- It increases fuel efficiency.
- Increases engine efficiency.
- Need less power input when operated manually.
Ans:-A Newtonian fluid possesses a linear stress strain relationship curve and it passes through the origin. The fluid properties of a Newtonian fluid do not change when any force acts upon it.
3.) What are the points in the stress strain curve for steel?
Ans:-Proportional limit, elastic limit or yield point, ultimate stress and stress at failure.
