To investigate forced and free oscillations under different damping conditions.
Key Features
- Copper wheel held on ball bearings which acts as an oscillating system (resonator).
- Periodic excitation through high sensitivity adjustment direct current gearing motor which acts on the exterior end of a spiral spring by means of an excenter and a lever.
- The other end of the spiral spring is attached to the axle of the resonator.
- Two potentiometers for coarse and fine adjustment of the motor; two pairs of 4 mm jacks for power supply of the motor and of the eddy current brake; pair of 4 mm jacks for direct connection of a voltmeter to the motor.
- Exciter and resonator have pointers; ring scale with slots for shadow projection; damping of the oscillating system through electromagnetic eddy current brake.
