Learning Objectives[^1]:
- To develop students' competence in the use of experimental tools for problem solving and design in the area of dynamics and vibrations (1,2,6)
- To provide opportunities for the students to practice communication and team-building skills, and to acquire a sense of professional responsibility, and to motivate and train the students to learn on their own (3,4,5).
Experiments: (Selected experiments from the following list)
- Cam Dynamics.
- Gyroscope and Gyroscopic Effects.
- Free Vibration of a 1-DOF System.
- Forced Vibration of a 1-DOF System due to a Rotating Imbalance.
- Forced Vibration of a 1-DOF System due to an Oscillating Support.

- Torsional Oscillations of Rotors.
- Torsional Oscillations of a Single Rotor with Viscous Damping (using Universal Apparatus).
- Damped Transverse Vibrations of Rigid Beams.
- Whirling of Shafts.
- Balancing of Rotors: Static and Dynamic Balancing.
- Balancing of Rotors using a Vibration Meter and a Phase Meter (Vibration Analyzer).

- Introduction to Vibration Analyser.
- Experimental Modal Analysis Using an FFT Analyser.
- Machine Condition Monitoring and Signature Analysis.
- Accelerometer and Vibration Level Calibration.
- Random Vibration: Methods of Analysis.
Computer Usage:
- For the experiments done, the students are required to use specialized software to acquire and analyse data, and to validate the results.
- Design of Experiment: Student teams are to be given which require the use of computer tools introduced.
- Laboratory reports are to be prepared by using appropriate computer-software (word processing, graphics, spreadsheets)
Evaluation:
- Exams.
- Quizzes.
- Reports.
- Oral presentation.
- Self and Team Assessment.
- Project.
- Lab participation.
