Aim: -

The aim of this experiment is to find out the amount of deflection is affected by the force applied to a cantilever

Apparatus: -

To carry out this experiment we will need the following apparatus –

Masses (In different proportions)

A measuring apparatus (Ruler)

1 metre stick (wooden)






Method: -

We shall place the wooden 1m stick across the table. We shall then leave most of it sticking out, and then attach it to the table using the g-clamp. Measure the current height the meter stick is at in its resting position (0mm). To measure the deflection of the ruler I will add a 100g weight then record the height of the stick by using the

 Physics for you

These two books helped me understand Hooke’s law of compression and expansion. While the preliminary work help me to determine a prediction.

Preliminary Work Results: -

Force Applied (N) & Results (mm)












Safety: -

We will have to be safe that the meter stick does not snap especially the in case shards fly out so will be taking minor precautions and shall not be adding ludicrous amounts of weight onto the stick. So I will be put a maximum of 6N on the meter stick.

The Equipment -

The equipment that we shall be using will be checked to see if there is anything wrong with it, for example the meter stick may already has a sleight bend within it. We will have to use the most accurate equipment available to us so we can obtain the most reliable and accurate possible results. Wood is the

My prediction matched the result due to an experiment on Hooke's Law which we conducted previously and because the two where connected we could roughly see what the results were supposed to be.

I also did some research using the Internet and found out the formulae for Hooke's Value, this is used for checking proportions.

Hooke's Value= Mass/Extension

In the graph and the tables that have been drawn the value is equal for the distance from the pivot and this shows that the proportion between the weight and the force applied is correct.

Evaluation: -

The experiment worked out to produce good and quite accurate results so we could plot a graph and draw a sensible conclusion. The results obtained were accurate enough but the was a few amorous results obtained when experimenting, this is due to bouncing and the level ness of the ruler used to measure deflection. Overall I thought the experiment was a success due to the fact that the results seemed to be very reliable.

    The extension increase was directly proportional up to the copper wires elastic limit, at which the original increase increased, and the wire never returned to its starting length. This caused it to be permanently deformed. Analysis: From my results, I conclude that the increase in load on a cantilever is directly proportional to an increase in weight.
