Forced Oscillators & Resonance SP761


Exp-1 To investigate resonance in forced oscillations.
Exp-2 To find spring constant of a spring.

  • System can be driven at various frequencies.
  • Bright LED display of frequency.
  • Easy to measure Amplitude.
  • Mass on the spring oscillates free or damped in water.

The apparatus consists of a mass attached to a spring, which is connected to a cord passing over a pulley and further connected to a drive wheel. The frequency of the drive wheel is displayed in “Hertz” on control unit display. Mass on the spring can be made to oscillate free or damped in a tube of water. The system can be driven at various frequencies and the amplitude can be measured with a scale.
