- Controlled variables:

- The width, breath and length are all constant for the experiment to me performed. Along with this, even the material of the scale and weight of it cannot be changed, as this would increase the uncertainty.

- The pump has to be used because the force has to be constant. Equal amount of water should be poured.

The Procedure:

- The cantilever has to be fixed on the flat surface. The cantilever should not move through out the experiment.

- Pour 10 ml of water in the beaker and put on a particular force on the pump and pour the water.

- Note down the deviation on the on the protractor and the time taken for 10 oscillations.

- Note down the time for the 10 oscillations.

- Leave the scale to oscillate about the mean position.

- Repeat the experiment from step 1 to 5 and carry it out for the particular force 3 more time.

- Then change the force on the pump and carry it out. For each time, note down the angle and the time taken for 10 oscillations.

- Each oscillation would mean from the start point to the extreme deviation to the initial point and then to the other extreme deviation and back to the initial.

- It is very difficult the start the stopwatch as soon as the oscillations start so it is advisable that for each time the experiment is carried out, the stopwatch should be started after 2 oscillations.

- For the time taken for10 oscillations, should be divided by 10 to find the time taken for one. The will be the time period of the cantilever.

- The entire procedure should be repeated with at least 10 different forces on the water.

- The will allow you to know, weather with different forces the time period changes and allow us to know the relation.

- The graph can allow us to find out the exact relation.
