FUNDAMENTALS OF MECHANICAL ENGINEERING & MECHATRONICS | KME201T
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.”
