Theory of Machines Lab Equipment: Complete List and Setup Guide

Theory of Machines Lab Equipment: Complete List and Setup Guide for Engineering Colleges

Theory of Machines (TOM) lab equipment covers the mechanical mechanisms, governors, balancing machines, gear systems, vibration apparatus, and cam-follower units required for B.Tech and B.E. mechanical engineering curricula. This guide provides a complete equipment list, experiment descriptions, and procurement guidance for engineering colleges setting up or upgrading their Theory of Machines laboratory to meet AICTE, NAAC, NBA, ABET, or CAA standards.

Standard Theory of Machines Lab Equipment List

1. Governor Apparatus

Demonstrates speed-governing mechanisms used in engines and turbines. Typically includes Watt, Porter, Proell, and Hartnell governor configurations on a single motorised spindle.

• Key experiments: Speed vs. radius of rotation; sensitiveness; stability; isochronism
• Scientico model: Governor Apparatus Manufacturer India

2. Dynamic Balancing Machine

Demonstrates static and dynamic balancing of rotating masses. Students add correction masses in specified planes to eliminate vibration from an unbalanced shaft.

• Key experiments: Static balancing; dynamic balancing; determination of balancing mass and angular position
• Scientico model: Dynamic Balancing Machine Manufacturer

3. Cam and Follower Apparatus

Studies the motion characteristics of various cam profiles (circular, tangent, involute) with different follower types (flat-faced, knife-edge, roller).

• Key experiments: Displacement diagrams; velocity and acceleration analysis; follower lift vs. cam angle
• Scientico model: Cam and Follower Apparatus Manufacturer India

4. Vibration Test Rig (Free, Forced, Damped)

Motorised vibration apparatus for studying single-degree-of-freedom systems, natural frequency, resonance, and damping ratio determination.

• Key experiments: Free undamped vibration; forced vibration; resonance frequency; logarithmic decrement
• Scientico model: Vibration Test Rig Manufacturer India

5. Gear Train Apparatus

Demonstrates simple, compound, reverted, and epicyclic gear trains. Students measure velocity ratios and understand gear ratio calculation in complex train arrangements.

• Key experiments: Velocity ratio of simple and compound gear trains; epicyclic gear train analysis; gear efficiency

6. Whirling of Shaft Apparatus

Demonstrates critical speed (whirling speed) of a rotating shaft — the phenomenon where shaft deflection is amplified due to resonance between rotational speed and natural frequency.

• Key experiments: Determination of critical speed; effect of shaft diameter and span on whirling speed

7. Scotch Yoke and Slider Crank Mechanism

Converts rotary motion to reciprocating motion. Used to demonstrate and verify kinematic analysis of slider-crank mechanisms including velocity and acceleration diagrams.

8. Motorised Gyroscope

Demonstrates gyroscopic couple — applied and reactive — relevant to the analysis of ships, aircraft, and automotive systems.

• Key experiments: Measurement of gyroscopic couple; precession and spin relationship
