Does an elastic band behave in the same way as a steel spring?


Clamp stand, rubber elastic band, 0.5N weights, 1 metre stick, clamp and pointer.


We set the apparatus as shown above. First of all we took the measurement on the metre rule in cm, of the elastic band at the pointer without any weights attached. Then we steadily increased the force by adding a 0.5N weight each time to the elastic band. We did this until we reached 3N, and then steadily decreased the force by carefully taking of a 0.5N weight each time, until we had no weights attached to the elastic band. Next we again took the measurement on the

Units on metre rule to record results (cm)

Person taking measurement

Amount of load added each time

Person adding and removing weights



Lastly, we worked out an average length in cm by adding the 3 results and dividing by 3. We then took 1 average from an other to work out the extension. As seen in the results table over the page.


My graph shows the relationship between the weight on an elastic band and its extension. The graph is not a straight line showing that’s its extension is not proportional to its load, disobeying Hooke’s law. My graph shows that the elastic band has been stretched because the unloading of weights has

Also, smaller weights would of given me a more accurate graph and results, from having smaller weights I would have a clearer idea of how differently a elastic band behaves to a steel spring. If I were to repeat my experiment again I would add only a 0.1N weight each time.

Lastly, I only went up to a maximum of 3N then back down, but with more time available I would of gone up to 6N to test the elastic bands elasticity, strength and to obtain more accurate results to find out exactly how a elastic band behaves.

    I think that if I did use a greater range of loads, I am sure that I would have ended up with the same theory that I already have. The experiment was very simple and thus the equipment was reliable as once it was set up by hand, I could

    * Tuck all stools under the desk in case the elastic bands snap and the weight shall fall. * The experiment will be carried out under the supervision of a teacher in case of any accidents. * Keep bags under the desk in case someone should trip and fall.

  1. An experiment to investigate and determine how rubber behaves when tension forces are applied ...

    This formula would be as follows: Tension (N) = Extension (cm) x Weight added to the rubber band (g) I predict that the formula that I have come up with will provide me with the information I need to find out whether the tension and extension are proportional and then I can lead on to explain why in my analysis.

    However if the temperature is raised then the heat energy will be transferred to the molecules, as the molecules vibrate more the bonds to weaken, resulting in the material expanding and become more stretchable. The bonds will also weaken if the band has been used frequently (this will heat the

    This shows that extension is directly proportional to the load. This is called Hooke's law. Preliminary Results: I have planned to put a weight of up to 880g and to start of at the elastic bands original with a load of 0g.
