Modal testing

    • Objectives:

      To measure the natural frequencies and vibration modes of a structural system and to understand the vibration concept.

  • Equipment:

    The experimental system includes an aluminum rod suspended by a pair of soft springs, an accelerometer, an instrumented hammer with a force transducer installed, spectrum analyzer, power supply and amplifier, and a PC based data acquisition system.

Gyroscopic Motion of a Rigid Body

    • Objectives:

      To study the gyroscopic effects on the motions of a rigid body.

  • Equipment:

    1. large steel sphere with an attached rod supported by a semispherical seat.

    2. compressor to levitate the sphere and to reduce the friction.

    3. Stroboscope, stopwatch, ruler.
