B.Tech (Semester II) – Theory Examination 2021–22

This document contains the complete and authentic B.Tech (Semester II) Theory Examination Question Paper for Fundamentals of Mechanical Engineering & Mechatronics (KME201T) for the academic session 2021–22. The paper comprehensively evaluates a student’s understanding of foundational mechanical engineering concepts along with introductory mechatronics principles. Covering stress–strain basics, beam loading, IC engines, turbines, refrigeration systems, pressure measurement, actuators, and control systems, this paper is designed to test conceptual clarity, analytical reasoning, and practical engineering knowledge.

The question paper is divided into three well-structured sections, each designed to assess different levels of learning: basic definitions, applied engineering concepts, and detailed analytical problem-solving.

SECTION A – Short Conceptual Questions (10 × 2 = 20 Marks)

This section includes ten brief questions aimed at testing fundamental concepts across mechanical engineering and mechatronics.

Topics covered include:

Young’s modulus, bulk modulus & Poisson’s ratio

Point of contraflexure in beams

Scavenging process in IC engines

Components of a vapor compression refrigeration system

Specific gravity of fluids

Range and span of measuring instruments

Calibration in measurement

Gauge pressure vs absolute pressure

Mechatronics: definition and key elements

Mechanical actuators

These questions ensure that students understand the basic definitions used in strength of materials, thermodynamics, fluid mechanics, refrigeration, metrology, and automation.

SECTION B – Applied Engineering Concepts (3 × 10 = 30 Marks)

Students must attempt any three questions. These questions require explanation, diagram drawing, engineering reasoning, and system-level understanding.

Major topics include:

Strength of Materials

Drawing Shear Force Diagram (SFD) & Bending Moment Diagram (BMD) for a cantilever with UDL

Calculating maximum bending moment

IC Engines

Working of a four-stroke CI (diesel) engine with neat P–V diagram

Turbines

Classification of turbines

Construction and working of Kaplan turbine

Pressure Measurement

Pressure definition

Bourdon tube pressure gauge: construction & working

Actuators & Mechanisms

Mechanical actuators

Kinematic chains, gears and types

Cams and followers

This section focuses on real-world systems, machine components, and their engineering behavior.

SECTION C – Long Analytical Questions (4 × 10 = 40 Marks)

Each subsection allows the student to choose one full-length question requiring calculations, diagrams, derivations, and detailed explanations.

Topics include:

3. Beam Analysis

Calculating shear force & bending moment

Drawing SFD & BMD

Composite bar problems: equilibrium, stresses & elongation

4. Refrigeration Systems

Working of Window AC

Domestic refrigerator with neat sketch

Components: compressor, condenser, expansion valve, evaporator

5. Fluid Mechanics & Hydraulic Machines

Pascal’s law

Hydraulic lift – construction & working

Centrifugal pump – components & working

6. Measurement Systems

Types of measurement errors

Radiation-based temperature measuring devices

7. Mechatronics & Control Systems

Open-loop vs closed-loop control systems

Hydraulic vs pneumatic systems

Directional control valve: construction, working & significance

These questions assess advanced understanding of mechanical systems, fluid power systems, thermal machines, and mechatronics components.

Sample Questions (1–2 included as requested)

Sample Question 1 (Section A):

“Define Young’s modulus, Bulk modulus and Poisson’s ratio.”
— A fundamental question testing knowledge of stress–strain relationships.

Sample Question 2 (Section C):

“Describe the Pascal Law. Explain the working of Hydraulic Lift with the help of a neat diagram.”
— A detailed explanation-based question from fluid mechanics.

These sample questions reflect the overall difficulty and pattern of the question paper.
