Pendulum (T212)

Subject Elec Eng

Set the values for the driving motor of a pendulum and observe its dynamic behaviour.

Update
Dear student, given the current situation and Government advice regarding Coronavirus (COVID-19), we may not be able to offer the usual level of support to our remote equipment at present. Our technical teams will endeavour to keep equipment available, but there may be occasions where issues take a little longer to resolve. In such cases you will receive guidance from the module team. Please continue to leave a message on the appropriate module forum if you encounter any issues with the equipment, these will continue to be monitored.

OEL 1: Controlling a driven Pendulum

The pendulum is controlled by a driving motor that rotates a vertical shaft back and forth in clockwise and anticlockwise directions. The pendulum is attached to this shaft by a horizontal pin, allowing it to rotate freely in a vertical plane. The driving motor can be set to oscillate regularly, moving the pin and the pendulum between left and right so that the pendulum swings back and forth. The faster the oscillating driving motor rotates the shaft, the greater the angle that the pendulum swings from the vertical. A sensor is able to read the angular displacement of the pendulum through time.

In this activity, you can set the values for the driving motor and observe the dynamic behaviour of the pendulum. This will enable you to experiment with the motion of the pendulum and its mathematical description as a sine wave, and to observe the relationship between its frequency, amplitude and phase.

Please be aware that all bookings are in UK local time.

It is recommended you check the connection to the laboratory in good time before you attempt an experiment. This is particularly important if, for example, you change equipment, browser, location, or are accessing through a corporate network. To check your connection to the laboratory, please visit this link using the computer, browser, and network you intend using.

Please note

Recent changes to the Firefox and Chrome browsers to prevent nuisance advertisements mean that sound has to be turned off by default, otherwise the video content will not load automatically. Both sound and vision are seen as important to the laboratory experience, so we recommend that you turn up the volume once you have entered an experiment. You will find the Volume control at the bottom right of the Video panel.
