Defence Research & Development Organisation Junior Research Fellow Interview Questions, Process, and Tips

kgF stands for kilogram-force, a unit of force in the metric system.

• kgF is a unit of force in the metric system, specifically equal to the force exerted by one kilogram of mass in standard gravity (9.80665 m/s^2).

• It is commonly used in engineering and physics to measure forces.

• 1 kgF is approximately equal to 9.81 Newtons (N).

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.

• Entropy in a closed system tends to increase over time

• Heat flows from hot to cold objects, never the other way around

• Efficiency of energy conversion processes is limited by the second law of thermodynamics

Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.

• It is a graphical representation of the behavior of a material under loading.

• The curve typically consists of three regions: elastic deformation, plastic deformation, and fracture.

• The slope of the curve in the elastic region represents the material's stiffness or Young's modulus.

• The ultimate tensile...read more

Gate and net scores for MSc and MTech with 60% and above.

• For MSc and MTech, a minimum of 60% is required in the qualifying exam.

• The candidate needs to clear the GATE exam with a good score.

• NET score is also considered for admission in some universities.

• Examples: MSc with GATE score of 70 and NET score of 80, MTech with GATE score of 80 and NET score of 75.

Yes, I have knowledge of pointers in C.

• Pointers are variables that store the memory address of another variable.

• They are used to manipulate data directly in memory.

• Pointers can be used to pass values by reference, allowing functions to modify the original data.

• Example: int *ptr; ptr = # *ptr = 10; // changes the value of num to 10
