Course details

This course is specially designed for mechanical engineering students, graduates, and professionals who want to confidently face interviews or viva exams. It covers over 100 commonly asked questions from core mechanical engineering subjects, including Basic Mechanical Engineering, Manufacturing Science, Material Science, Strength of Materials, Theory of Machines, Automobile Engineering, Fluid Mechanics, Thermodynamics, Refrigeration & Air Conditioning, Heat & Mass Transfer, and more. Each question comes with two types of answers: an easy-to-understand, practical explanation and a more theoretical, interview-ready version. The questions are categorized into easy, medium, and hard levels, helping learners gradually build their knowledge. By going through this course, students not only prepare for interviews and viva but also strengthen their academic understanding. The focus is on making learning simple, practical, and applicable, so you gain both confidence and expertise. Whether you are a final-year student, pre-final-year student, or working professional, this course guides you step by step to master mechanical engineering concepts and face professional challenges successfully.

Questions and Answers

Q: You're reviewing a GA from a supplier and googling "true position vs concentricity interpretation on rev 4 drawing" because the bore axis callout seems off. The drawing shows ⌀0.15 true position relative to A|B on a Ø40 bore, but no diameter symbol in the FCF. What does that actually control in assembly?

Q: During cold start you search "pump cavitation low NPSHa operator response" after suction pressure drops by 0.3 bar. Flow is steady, vibration rises, and discharge pressure wobbles. What's the least damaging immediate response?

Q: You're sanity-checking a calc and type "worst case tolerance stack up calculation 0.2 mm". Three parts stack in series: ±0.10, ±0.05, and ±0.05 mm. Assembly requires minimum 0.10 mm clearance. Using worst-case, what clearance do you document in DFMEA?

Q: On site for pre-commissioning, you google "loop check transmitter before energizing final element". A pressure transmitter feeds a PLC which drives a control valve. What gets verified first during a cold loop check?
