Hooke’s Law

The aim of my investigation is to find out if Hooke’s Law can be proved with a steal spring and to see what would happen if the spring is stretched beyond the elastic limit.


In this investigation the following safety rules were applied:

  • Long hair was tied back to prevent it from getting in the way.
  • People were not cramped together as they needed room to work.
  • Goggles were worn to prevent eyes from getting damaged.
  • People could not play with equipment.
  • People could not run around in the science laboratory.
  • Desks were cleared.

There were not to many strict safety precautions used, as the only potential danger was if the spring snapped.

      My method of experimentation will be to use a clamp stand and boss clamp to suspend a spring from. A second boss clamp will hold in place a metre rule starting from the bottom of the spring to measure extension in cm. I will then add weights to the spring and measure extension. As I am doing this, I will record my results in a table. I will continue to do the tests until the spring will not return to its original shape. To make the tests fair I will use the same spring and set of weights each time.

My results are meaningful as they support my objective. I placed them in a table to make them easier to identify.  I did not need to take repeat readings, as I found them reliable andaccurate when I noticed that the spring started to follow a pattern

If the experiment were to be carried out again, changes could be made to reduce experimental error. The ruler suspended by the spring could have been set vertically by using a plumb line. Also a pointer on the spring would help in gathering the information more accurately. If the measurements were to be taken even more precisely then an ultra sonic measuring device could be used to measure the extension to a very accurate degrees.  However, my results are reasonably reliable as all of them were very close to the line of best fit.

I do consider my results good enough evidence to support my conclusion as most of them followed a steady pattern and showed that if you stretch something with a steadily increasing force, then the length will increase steadily too. Some of my results were anomalous as when they were approaching the elastic limit the results started increasing in different amounts.  

If I would carry on with my experimentation, I would find out what happened after the limit of proportionality had been reached using Hooke´s law, achieving results until the spring became straight and eventually breaking. However the change in length at this stage is very small and special measuring equipment would be needed in order to conduct a reasonable experiment.

  1. Hooke's Law.

    For example, if the load/stress is doubled, then the extension/strain would also double. However, there is a limit of proportionality (which is often also the elastic limit), only up to which Hooke's Law is true. Since the strain is proportional to the stress for different materials where Hooke's Law is

    It may also have been caused by a change in the temperature of the lab at the time when the load was applied to the stretchy sweet, as a change in temperature will cause the stretchy sweet to expand or contract.

This is especially evident if the spring constants are approximated, as doing this cuts out some of the experimental error (due mainly to the difficulty of reading results as will be discussed later)

    This shows that Hookes Law does have a limit as a spring does and does have limitations and if kept within these boundaries will provide reliable accurate results. Hooke�s law can also be explained by the molecular structure of the substance the force is acting on: F Sep 1.

    I have also noticed that the steeper the gradient the more easier the material is to stretch. My prediction was correct and what I found supported my prediction. I did find that none of the bands obey Hooke's Law because of the bands elasticity.
