Can you provide me some questions from the Technical Section of the Placement Exam of Jindal Steel & Power Ltd as I need it for preparation of the exam?

[Vishal Kotkar]

Some questions from the Technical Section of the Placement Exam of Jindal Steel & Power Ltd are as follows:

It consisted of following questions:-
1. The process of joining two metals is— sintering, thumbling, coining?

2. Ratchet is provided in micrometer screw gauge to-maintain uniform pressure…

3. Strain energy is -the energy stored up to elastic limit..

4. Taper angle is measured by-Sine bar, bevel protector?

5. A centrifugal governor is – Hartnell, Porter, Proell?

6. Numerical on Gate design?

7. Equivalent length in saw is measured from- start point to finish point, from first teeth to last teeth?

8. Anemometer is used for measuring- temperature of air, velocity of air, viscosity
of fluid?

9. In neutral equilibrium position of meta center is- coincides with center of gravity..

10. If young’s modulus increases what is the change on thermal coefficient of expansion..?

11. Kaplan turbine- low head, high discharge..

12. Strain- (L-l)/L..

13. Economisor is used for-pre heating feed water..

14. In reciprocating compressor clearance is provided for- cushioning effect and saves the piston from hitting the cylinder head..

15. Function of governor is- maintain a constant speed in parting load conditions..

16. Heat Transfer from hot body to cold body takes place without affecting intervening medium is-radiation..

17. When conduction will not take place-when temp. of both bodies are equal..

18. Which of these defines pitch circle diameter-circular pitch, module,diametral pitch(all of these)..

19. Which of these governor is known as dead weight governor- Portor governor..

20. Property which resist elastic deformation-stiffness..

21. Continuous beam is a beam with- more than 2 supports..

22. More than two supports is known as continuous beam..

23. For self locking of screw-helix angle > friction angle..

24. Involute profile is preferred in gears as-it transmits maximum power..

25. The gear which resists axial thrust-herringbone gears..

26. For large power transmission, square threads- wear out, less efficient, production is costly..

27. The weakest part in flange coupling is-key..

28. Cage is provided in ball bearing to –keep balls in position..

29. When a mass of critically damped style, degree of freedom of system is deflected from its equilibrium position and then it is released then-it will oscillate with increasing time period.

30. 30(+0.05)(-0.03) is- bilateral type of tolerance..

31. Numerical on hoop’s stress?

32. When a cylinder is compressed over another then-hoop stress is reduced.
