Description:-
The frequency of the drive wheel is displayed in Lab Connection on control unit display. 
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. 
Mass in the spring can be made to oscillate free or damped in a tube of water.
The amplitude can be measured with a scale. 
The system can be driven at various frequencies.
Feature:-
