Elasticity Investigation

Extracts from this document...


Elasticity Investigation AIM In this experiment, we aim to investigate the stretchability of some materials when weights are attached to them. Certain wires/springs/elastic bands will stretch, and will go back to their shape and size, once the material has been let down. Other materials will stretch and then will not go back to their shape. This experiment can be used to simulate how car springs work. to give comfort as you drive along The springs mainly found in the suspensions of cars. These springs will need to be capable of being compressed and extended, several times, and then return back to their previous state in size and shape. The two forces that mainly affect the springs, is compression and extension [this force rarely occurs]. Compression is the weight of the car [which includes the occupants] Extension is due to the 'wheels up and down' energy not being transferred back to the body of the car. ...read more.


After attaching the weights, the material length, will then be measured again. This new length, is the extension length. The difference between the original length and the extended length, is the extension of the material. The experiment is repeated for all the weights [some materials will break/not stretch any further before the full 10 Newton weight is put on], and also for all the materials that are being tested. For safety during the experiment, safety glasses will be worn, in case if the spring breaks under tension, the broken piece will not go into our eyes, and therefore damage them. Also in case the weights fall to the ground, there will be an area where any person cannot enter, but only by the person attaching the weights onto the material. RESULTS Load (in N) ...read more.


From the results I conclude this, due to that the elastic band stretched furthur than the spring on each weight, but then did not return to the shape and size it had previously. The other result for the other materials, has not been used, because the results were not correct, in the way of the extended length and the extension. Out of the two springs used in the results, I conclude, that the best performer in retaining its original size and shape, is a spring that is taut. This disproves my hypothesis. The taut spring is the best because of the way it keeps its shape, but if this tautness of spring was fitted to a car, it would not be very comfortable to ride in. Also after a while there may be damage to the chassis of the car, because the full force is affecting it, and not being sufficiently absorbed by the spring. ...read more.

    Box White and Black Paper Ruler Connecting Wires From my preliminary experiment I am able to make some modifications to my final experiment. These are to repeat my experiment 3 times.

  2. Investigation into the elasticity of a set of springs under different conditions.

    Showing that as the load increases the extension will increase proportionally. But this only resembles a single spring on its own. Having springs in parallel or in series will effect the springs constant. I predict that the springs in parallel will half the spring constant and when the springs are in series the springs constant should double.

  1. Investigating elastic bands in comparison with springs.

    This is because as the spring is stretched, up to it's elastic limit, it uncoils and is strong enough, as Hooke's law states, to return to its original form. The band however, I think will be weaker as once the particles have been unravelled from the weight of the load, they will find it hard to restore their original shape.

  2. Investigation into the elasticity of a set of springs under differing conditions.

    The definition of Hookes law is as follows: An object obeys Hookes Law if the extension produced in it is proportional to the load. I expect that the spring stiffness (k) will change depending on the arrangements of the springs i.e.
