(SEM I) THEORY EXAMINATION 2020-21 FUNDAMENTALS OF MECHANICAL ENGINEERING & MECHATRONICS

This document contains the official AKTU B.Tech 1st Semester (2020–21) Theory Examination question paper for Fundamentals of Mechanical Engineering & Mechatronics (KME101T). It is a full 100-mark, 3-hour exam paper designed to test the essential concepts of thermodynamics, IC engines, refrigeration & air-conditioning, mechanical properties of materials, fluid mechanics, hydraulics, control systems, measurement, and mechatronics.

This question paper strictly follows the AKTU formatting and is extremely useful for students preparing for semester exams, internal assessments, and practical viva. It provides complete coverage of the syllabus through conceptual, numerical, and diagram-based questions.

Detailed Structure and Topic Coverage

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

This section consists of 10 short, basic questions, ideal for concept recall and quick scoring. Topics include:

Internal combustion (IC) engines

Poisson’s ratio

Coefficient of Performance (COP) of a refrigerator

Newtonian vs Non-Newtonian fluids

Accuracy vs precision

Pressure control valves

Open loop vs closed loop systems

Hooke’s Law

Tolerance

Scavenging process

These questions help students build strong fundamentals.

SECTION B – Medium-Length Questions (3 × 10 = 30 Marks)

Students must attempt any 3 out of 5 questions. Topics include:

Two-stroke SI engine (working + neat diagram)

Hole basis vs shaft basis system (with diagrams)

Hydraulic pumps – definition & types

Working of domestic refrigerator (with diagram)

Autotronics, bionics, avionics – meaning & applications

This section tests explanation ability, diagram practice, and technical clarity.

SECTION C – Long Answer Questions (5 × 10 = 50 Marks)

Each question has two alternatives; students must attempt one part from each question.

Q3 – Thermal Engineering / Measurement

Four-stroke CI engine (construction + working + neat sketch)
OR

Measurement errors & methods to minimize them

Q4 – Fluid Mechanics / Strength of Materials

Pascal’s law and practical applications
OR

Stress-strain diagram for ductile vs brittle materials

Q5 – Hydraulics / Mechanics

Hydraulic turbines – classification, advantages, disadvantages
OR

Types of beams (cantilever, simply supported, fixed, etc.)

Q6 – Refrigeration / Control Systems

Window air conditioner – construction & working
OR

Control systems – definition & major elements

Q7 – Mechatronics / Sensors

Mechatronics – definition, advantages, disadvantages, applications
OR

Sensors & transducers – definition & types

This section is scoring and helps students master high-weightage concepts.

Why This Question Paper is Important for Students

This AKTU question paper is highly valuable because it:

Shows the exact exam pattern and question difficulty

Helps practice repeated questions and core engineering concepts

Covers all key topics from mechanical engineering and mechatronics

Improves diagram practice (engines, air conditioners, stress-strain curves, hydraulic systems)

Strengthens fundamentals for subjects taught in later semesters

Boosts exam confidence through complete syllabus coverage

Perfect for students aiming for high marks in KME101T.
