About this previous year paper
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.
