SSB Interview Questions for Mechanical Engineering: A Comprehensive Guide

SSB (Selection Board) interviews are a crucial step for candidates applying to prestigious military academies or engineering programs. For mechanical engineering students, these interviews often test their knowledge through a series of technical questions. In this guide, we will explore key topics and questions that are commonly asked during SSB interviews in the field of mechanical engineering. This comprehensive resource will help you prepare thoroughly and effectively.

Thermal Engineering and Thermodynamics

Thermodynamics is a fundamental topic in mechanical engineering and is often tested in SSB interviews. Here are some critical questions you might encounter:

State all the laws of Thermodynamics (H1) State the difference between Unilateral and Bilateral Tolerance (H2) State 1st Law of Thermodynamics (H2) State the difference between AnitiFriction Bearing and Journal Bearing (H2) What is the importance of Thermodynamics (H2)

Mechanical Systems and Applications

Questions on various mechanical systems and applications are also common in SSB interviews. Here are some of the questions you can expect:

What is the difference between Critical Speed and Whirling Speed (H2) How a Diesel Engine Works as Generator (H2) What is the difference between P11 and P12 Pipes (H2) Explain the difference between LPG and petrol in cars (H2) State the difference between Speed and Economic Speed (H2)

Mechanical Engineering Principles and Components

Understanding the principles and components of mechanical engineering is essential. Here are some key questions to prepare for:

What is the purpose of Scrapper Ring (H2) What is DTSI Technology (H2) What is the purpose of a scrapper ring (H2)? What is the difference between Speed and Economic Speed (H2) What is the difference between AntiFriction Bearing and Journal Bearing (H2)

Mechanical Properties and Phenomena

Knowledge of mechanical properties and phenomena is also important. Here are some of the relevant questions:

Which has more efficiency: diesel engine or petrol engine (H2) What is the difference between sudden force and impact force (H2) How does heat affect the hole diameter in a steel pipe (H2) How can you determine if air is fully saturated (H2) What is the operating pressure (H2)

Comparison of Cycles and Machines

Questions comparing different cycles and machines are common. Here are some of the related questions:

Compare Brayton Cycle and Otto Cycle (H2) What is the difference between Speed and Economic Speed (H2)

Welding, Brazing, and Metal Tolerances

Welding and brazing techniques, along with metal tolerances, are also tested. Here are some of the relevant questions:

What is the difference between Welding and Brazing (H2) State the difference between Unilateral and Bilateral Tolerance (H2)
