VIRTUAL EXPERIMENTS

Set-Up Description

For conducting the experiment, the ball (with hook) is supported by a nylon thread tied to the hook. The length of the pendulum is varied between readings. This makes it possible to study the effect of Variation of Length on Time-Period of vibration. Also, a small ball may be substituted by a larger ball, for the same length of pendulum, to illustrate the effect of the Mass of Ball on the Time-Period of vibration.

Procedure for calculating time period:

1. Enter the values in Calculate Result tab.
2. Press the Calculate button.

Procedure for performing Practical:

1. Support the rod by means of two strings onto the main frame.
2. Adjust the length of the rod, the distance between the strings, and the string length as desired.
3. Allow the bar to oscillate in the plane containing the rod (horizontal plane) for a specific number of oscillations, and find the time period of vibration.
