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

Extracts from this document...

Introduction

Investigation into the elasticity of a set of springs under differing conditions. Preliminary investigations. The object of this investigation is to discover how springs react to differing situations. I plan to implement several strategies to discover this. I plan on beginning by ensuring that each of the springs are as similar as is possible, I plan to do this by checking that each of the springs are the same length and that they have the same no. of coils. I will conduct the experiment as scientifically as possible; this will be done with the use of accurate tools and the careful tabulation of the results. I will be taking into account the: Variation in the extension of the spring. How the springs are affected with the changing of weights. How the springs are affected when the way in which they are placed is changed i.e. in parallel, series and also when they are on their own. Another product of this experiment will be the proving of Hookes law: K = F / X Spring Stiffness = Force / Extension T = 2 mass K x g (Spring Stiffness is also measured by the gradient of the graph) Where : T = Periodic Time (s) K = Spring stiffness G = Acceleration due to gravity (m/s) ...read more.

The experiment will be laid out as follows: Clamp Stand Metre Rule Spring Load (weight) Desk Spring Marker I believe that this set up will provide the most accurate results and will also be the most efficient tactic to maintain consistency in the results. I will ensure that the distance between the top of the clamp stand and the ground will be kept at a maximum, this is because I do not want the spring or the load to hit the ground whilst the experiment is being conducted. Safety and Precautions. I will ensure that the experiment is completed safely by ensuring that all of the loads are safely secured onto the clamp stand. I also plan on ensuring that the springs are placed onto the clamp stand and do not snap, I hope to do this by not placing too many loads onto them, they are dangerous as they are very unreliable and may break if extended too much. Ensuring correct results are gained. I will also ensure that all weights are the correct weight, this is important as they may be the wrong weight. This will affect the results as the springs may be extended too much or not enough. To make the readings as accurate as possible I will add a piece of plastic or straw to the bottom of the weights, this will be used as a pointer to the metre rule. ...read more.

Conclusion

* A more advanced stop clock (possibly motion sensitive). * Better springs. I have also recognised that there are many errors in the experiment, most are based on human error but some are due to inaccuracies in the equipment. 1. Human Errors. * Timing - there are errors in the timing as peoples reaction times are at best 0.2 seconds. This means that the times could be inaccurate. * Counting the Oscillations - errors can be made when counting oscillations as your attention may be diverted. 2. Mechanical Errors. * Weight/Force - the weights used may have been inaccurate. * Springs - each oscillation would not have been the same as the rest as a result of the individual springs. The oscillation may have been larger or smaller. * Ruler - the rulers are accurate to the nearest millimeter, there may be errors when calculating the precise extension. Over all the experiment was a success apart from the occasional error described above. The results proved conclusive and have conformed to my predictions. The extension of the spring did halve when the springs were changed from single in series to two in parallel etc. the graphs can be used to help prove hookes laws and also to derive them. The changes that could have been made are minimal and may not have affected the results greatly. ...read more.

    At this point the molecular bonds are broken, (in reality this occurs at a point of least bond strength, due to the probable existence of minute quantities of 'lower bond strength' impurities in the material). Method The method I have chosen for this investigation involves first obtaining an elastic limit

  1. Investigation on how putting springs in series and parallel affects their extension.

    and take a repeat set of results to ensure the reliability of my findings. In order to attach the weights to the springs I will use copper wire. The mean of my 1st and my repeat set of results will be calculated for the single spring, the two springs in parallel and the two springs in series.

  2. Investigating Hooke's Law

    Also I will go up in equal increments so that when I work out extension according to Hooke's law the extension should be equal more or less throughout the investigation. I will also be repeating my investigation because by having to sets of results I wish to find an average to increase the reliability of the results.

  1. Investigating Hooke's Law into thin wires.

    The safety of myself and others is very important in the lab. In order to make the experiment as safe as possible I am going to ensure that the following requirement is satisfied: ?Everybody must wear safety goggles just in case the fishing wire breaks.

  2. Investigating the Vertical Oscillations of a Loaded Spring.

    I will use springs, which have the same length to start off with. I will record the time to the nearest 2 decimal places. Analysis: As I said above I shall use two separate methods to work out elastic constant.

  1. Investigate stretching using Hooke's Law.

    The measurements that I will be taking must be done as fairly as possible or the results shall not be accurate. The materials should be weight at the side of the table, so if it does snap it won't harm anybody.
