To test three different springs.

Extracts from this document...

Introduction

Aim:- To test three different springs. Spring one has the length of 55.5 Spring two has the length of 59 Spring three has the length of 60.3 I want to find out how much mass the spring can take before not being able to go back to its orginal state. Scientific knowledge: - Hook's Law if you stretch something with a steadily increasing force, then the length will increase steadily two. ...read more.

Middle

The point the straight line ends up at is the elastic limit. Apparatus: - clamp stand, ruler, 3 different types of springs and some weights. Fair test: - To add the same amount of weight on each spring. But some of the weights will be able to take more mass then the other ones. Safe test: - Wear safety glasses, lab coats and tie long hair back. ...read more.

Conclusion

Then take down your results. Results:- Spring 1 Mass Kg Extension cm 55.5 50g 0 100g 0 150g 0.1 200g 0.4 250g 1 300g 1.8 400g 1.9 Spring 2 Mass Kg Extension cm 59 100g 2 150g 3.7 200g 5.7 250g 8.5 300g 10.5 Spring 3 Mass Kg Extension 60.3 100g 2.4 150g 4.1 200g 6.2 250g 8.7 Evaluation: - My experiment did not go to well as it was not a fair test as some of springs got more weight then the other springs. And that my graph did not go in a straight line so it didn't follow Hook's law strictly. ...read more.

  1. An investigation into the behaviour of springs inparallel when a mass is applied.

    to carry out my preliminary experiment as I needed to find a mass that would stretch 1 spring within its elastic limit and also stretch 6 springs s that a reading could be gained. Also following Hooke's law it states that the extension of a spring is a to the force being exerted on the spring.

  2. Investigation on springs.

    * There is a danger that when too many weights have been added to the spring that the spring will uncoil, drop its weights and spring into the air therefore goggles must be worn to protect eyes from spring. Prediction Hooke's Law states that the extension is directly proportional to the stretching force".

    and was appointed Gresham Professor of Geometry at the University of Oxford in 1665. After the Great Fire of London in 1666, he was appointed surveyor of London, and he designed many buildings, including Montague House and Bethlehem Hospital. Hooke anticipated some of the most important discoveries and inventions of

  2. The Stiffness Of Springs

    However, 9.81 is an awkward number to use. Instead I am going to use 10 ms -2. I now have all the information I need to plan a simple experiment to show the spring constant of a spring. Equipment Here is a list of equipment I will needs: Springs (with a similar or identical stiffness)

  1. Investigate Whether Elastic Bands and Springs Behave the Same Way.

    band and spring as well), to prevent this I will use 3 different elastic bands and springs of the same size and width. Due to limited resources I cannot control the temperature, therefore preventing me from experimenting with this variable.

  2. An Experiment To Examine the Effect of Springs In Parallel

    The extension will decrease and will be half the original extension because there are now two springs to share the load. The molecules in each spring have half the amount of force acting on them now, than when there was only one spring, so they are not stretched apart that much.
