Period of a Loaded Cantilever

Design

Aim: To investigate the relationship between the mass loaded on a cantilever and the period of oscillation of a loaded cantilever

Variables:

Independent variable: Mass loaded on a cantilever

Dependent variable: Period of oscillation of the cantilever

Control variables:

Amplitude

Maximum displacement of the end of the cantilever

Can be kept constant by measuring the amplitude of each trial

Length of the cantilever

Can be kept constant by measuring the length of the cantilever or using the same model through the experiment

Air resistance

Different width of cantilever may have different air resistance. Kept constant by using a cantilever with the same cross-sectional area or simply use the same cantilever throughout the experiment. Carry out the experiment at room air density.

Stiffness of the cantilever

Kept constant by using the same cantilever of the same material throughout the experiment

Apparatus:

1

2 Meter sticks

One Meter stick as a cantilever and the other to measuring the amplitude of oscillations

2

Masses

Masses to be loaded on the cantilever as the
