Description:
The Applied Mechanics Lab at BAUET is designed to provide mechanical engineering students with hands-on experience in analyzing mechanical motion, dynamic systems, and the principles of vibration and rotational mechanics. This lab plays a crucial role in deepening the understanding of Engineering Mechanics and Theory of Machines, which are fundamental subjects in mechanical engineering education.

By experimenting with real mechanical systems, students gain insight into the behavior of rotating bodies, vibrations, balancing, and mechanical governors, which are essential in the automotive, aerospace, and machinery design industries.

  1. Governor Apparatus

Demonstrates centrifugal governor principles (e.g., Watt, Porter). Students examine how governor sleeve positions vary with speed and load, enhancing understanding of mechanical speed regulation and stability.

  1. Free and Forced Vibration Apparatus

Allows analysis of single-degree-of-freedom systems under free and externally forced vibration. Students can study natural frequency, damping effect, and resonance phenomena. Essential for understanding vibration control in mechanical structures and machines.

  1. Gyroscope Apparatus

Demonstrates the principles of gyroscopic couple and precessional motion. Helps students explore the dynamics of rotating bodies in aircraft, ships, and motorcycles. Useful for analyzing the stability and directional control of moving systems.

  1. Static and Dynamic Balancing Apparatus

Used to investigate the balancing of rotating masses in static and dynamic conditions. Allows practical balancing of rotors and shafts to reduce vibration. Important for improving the performance and life of rotating machinery.

  1. Whirling of Shaft Apparatus

Demonstrates the phenomenon of whirling (critical speed) in rotating shafts. Allows determination of natural frequency and observation of shaft deformation at various speeds. Crucial for safe design of drive shafts, turbines, and rotor systems.
