Practice questions

These are practice questions, not verified company interview questions.

1. What is the difference between heat engine and heat pump? A heat engine converts thermal energy into mechanical work, while a heat pump transfers heat from a colder area to a warmer area using mechanical work.

2. Explain the concept of entropy in thermodynamics. Entropy is a thermodynamic state property with units J/K; for reversible heat transfer, dS = δQ_rev/T. Entropy generation measures irreversibility, and T₀S_gen gives destroyed exergy relative to an environment at T₀; entropy itself is not energy.

3. What are the different types of gears and their applications? Common types of gears include spur gears, helical gears, bevel gears, and worm gears. Each type is used in different applications based on factors like speed, torque, and direction of force.

4. How does a four-stroke engine work? A four-stroke engine operates through four stages: intake, compression, power, and exhaust. Each stroke corresponds to a movement of the piston within the cylinder.

5. What is the significance of the Reynolds number in fluid mechanics? The Reynolds number is a dimensionless quantity used to predict flow patterns in different fluid flow situations. It helps determine whether the flow will be laminar or turbulent.

6. Describe the process of metal casting. Metal casting involves pouring molten metal into a mold cavity, allowing it to cool and solidify, and then removing the cast part from the mold.

Before the interview

• Review your academic projects and be prepared to discuss them in detail.
• Reflect on any internships or practical experiences, focusing on what you learned and how it applies to the role.
• Research Cummins India's recent projects, innovations, and company values to understand their business better.
• Prepare questions to ask the interviewer about the company and the role.
