1. Subject Overview – Theory of Machine
Theory of Machine (TOM) is a crucial subject in mechanical engineering. It focuses on understanding machine parts in motion, their relative motions, and the forces involved. Topics include:
-
Kinematics of mechanisms
-
Cams and followers
-
Gears and gear trains
-
Flywheels and governors
-
Balancing of rotating masses
-
Dynamics of reciprocating engines
Students learn how energy transfer, motion transmission, and mechanical efficiency play roles in real-life systems like vehicles, engines, turbines, etc.
(Expand to 100–120 sentences covering practical relevance, industrial applications, and real-life examples of TOM concepts.)
🧠 2. Why MCQ Practice Matters
MCQs help students revise wide topics in less time.
-
They're commonly asked in polytechnic semester exams, competitive exams (like JE, SSC JE, DRDO Tech), and placement tests.
-
They test conceptual clarity, speed, and accuracy.
-
Practicing topic-wise MCQs makes theoretical understanding strong.
Topics covered in TOM MCQs:
-
Types of links & joints
-
Velocity diagrams
-
Types of gear trains
-
Inversion of mechanisms
-
Force analysis in machines
(Explain benefits of MCQ practice, timing strategies, memory tricks, and exam pattern insights in 100+ sentences.)
📚 3. Topic-Wise MCQ Breakup
🔹 Kinematic Chains & Mechanisms
-
Types of kinematic pairs
-
Degrees of freedom
-
Inversions of 4-bar and slider-crank mechanism
🔹 Gears & Gear Trains
-
Spur, helical, bevel gears
-
Gear ratio, velocity ratio, torque transmission
🔹 Cams and Followers
-
Types of followers, motion of follower (SHM, uniform velocity, etc.)
-
Pressure angle, displacement diagrams
🔹 Governors & Flywheel
-
Types of governors: Watt, Porter, Proell
-
Working principle, sensitiveness, isochronism
🔹 Balancing
-
Balancing of single/multi-rotating masses
-
Concepts of reciprocating balancing
(Each of the above 5 sections should have ~30–40 sentences: define terms, sample MCQs, how to attempt, and common mistakes.)
