How the extension of the spring will change or vary, when force is applied.

Extracts from this document...


How the extension of the spring will change or vary, when force is applied. Aim My aim is to see how the extension of the spring will change or vary, when force is applied. The variable in this investigation is the weights. Other possible variables that can be investigated are the different materials of the spring. Fair Test It will be a fair test because the same steel spring will be used on all of them. I will check that it has not reached its elastic limit. I will make sure that while the weights are on the spring, the spring should be still. Equipment Steel spring 8x 1N weights Clamp Stand Meter stick/ruler The measurements that I will need to take are the different lengths of the spring when it has different weights on it. There will be 8 different measurements of the length of the springs. The weights will range from 0.1kg to 0.8kg. The best way to carry out the experiment is to use a stand and attach a clamp to it, you should hang the spring on it and add the weights. ...read more.


I plan to take 8 or 10 readings of the length and weight over a wide range of values. Prediction I predict that if you double the load, it doubles the extension and if you put on 3 times the load it will treble the extension. I predict this due to Hooke's Law. Hooke's law is when: The extension is directly proportional to the stretching force Due to this law I predict that when I plot a graph of showing the extension, it will go up in a straight line. When it reaches its elastic limit then it will curve. Results Table Mass of load Weight of load Initial length of spring (cm) Final length of spring (cm) Extension (cm) 0 0 3.2 3.2 0 0.1 1 3.2 7 3.8 0.2 2 3.2 10.6 7.4 0.3 3 3.2 14.3 11.1 0.4 4 3.2 18 14.8 0.5 5 3.2 21.5 18.3 0.6 6 3.2 25.3 22.1 0.7 7 3.2 28.7 25.5 0.8 8 3.2 33.5 30.3 Graph results The graph shows that the gradient is positive as it is going up. ...read more.


Evaluation I thought that the method I used was quite accurate because I got the right results and I managed to prove Hooke's law. The experiment did not take too long to do. In my results I only had one anomalous result. This was for 8N because I got 4.8 for the extension whereas all the rest were in between 3.4cm and 3.8cm. I think this is becauseit was losing its elastic limit. To make the results more accurate I could put a pointer on the end of the spring so I would be able to read the results more accurately. I should have done each experiment three times and then found the average, this would have been more accurate instead of just doing it once. Even though I did not do these things to make it more accurate, my results were reliable enough. Further work I could use different springs like copper, brass or anything. I would compare the forces required to stretch them and see which spring was the best and which would exceed its elastic limit first. Harpreet Sekhon ...read more.

    The results fit my prediction well as I predicted that the results would be proportional, and the results are roughly proportional. These results support my original theory well. Evaluation I think that my plan went well, and I have proved what I set out to prove.

  1. The aim of this investigation is to examine the effect on the spring constant ...

    Applying this to the above equation produces a fairly accurate approximation for the gradient of the line of best fit and as stated earlier, this result is also the system's spring constant. These values have been compiled to form the following table: Single Series Parallel Avg of 1st 5 ext's (x1)

    Some variable will need to be changed. As I am measuring springs in parallel I will need to change how many springs will be bearing the weights. Also the amount of weight on the hanger will have to be changed each time (1-5N).

    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.

    This is done to stop the stand from toppling over. Procedure After I have set all the equipment in to place. The experiment will be started with zero weights on it. The reading on the ruler will be taken and then the 100g weight will be put on the hanger one weight at a time.

  2. Stretching Springs/Hookes Law.

    This relationship is known as Hooke's Law after the British physicist Robert Hooke, who first expressed it. However, if the external force is too strong, the material can become permanently deformed, and Hooke's Law no longer applies. The maximum amount of stress a material can withstand before becoming permanently deformed is called the elastic limit.
