Forced Oscillators & Resonance

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 when damped in a tube of water. The system can be driven at various frequencies and the amplitude can be measured with a scale.

Features:

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

Experiments:

• To investigate resonance in forced oscillations.
• To find spring constant of a spring.
