# Investigating the Elasticity of a Rubber Band

Extracts from this document...

Introduction

Investigating the Elasticity of a Rubber Band

Introduction:

An elastic material is a material, which will return to its original length when a load is added and taken off, but if you reach the elastic’s elastic limit then the elastic becomes plastic, this is called Hook’s Law.

I am going to investigate the elasticity of 1 rubber band by hanging it off a clamp which, is attached to a clamp stand and adding a load onto the rubber band.

‘ Apparatus:

A long clamp stand,

A clamp,

A boss,

A meter ruler,

A pin,

A mirror,

A long thin rubber band,

100g Masses.’ (1 Newton weights)

The variables in this

Middle

First of all I setup the apparatus and made sure it was all safe and secure, I then took a measured the length of the rubber band while it didn’t have any extra mass on. I then started to add on a mass of 100g I took the reading using my pin, mirror and ruler and recorded it in a table. I kept adding 100g onto the rubber band and recording it using my pin, mirror and ruler until I reached a mass of 1500g. From my results I then

Conclusion

Evaluation:

I think that my results are reasonably accurate if you take into to account the fact that I was not in a high sophisticated laboratory with precision recording equipment. There was one result, which didn’t fit into the pattern of results because it was anomalous. I included the measurement in my table of results and also plotted it on my graph but missed it out when I drew the line of best fit. The experiment could be improved by measuring the length of the rubber band when removing the mass.

1. ## Investigation on whether Rubber obeys Hooke's Rule

3 star(s)

Variables - * Tension force - this is the variable that will be changed manually by using varied weights. Constants - * Size, shape and surface area of the rubber will be kept constant. * Material will be kept constant.

2. ## Does a rubber band obey Hooke's law?

I took one set of readings for my results. I could have improved my work by doing the following: * I could have taken two sets of readings to increase the accuracy in my results, and reduce the chances of an anomaly.

1. ## Investigate the way in which extension depends on the tension for rubber.

This will hook onto the elastic band and the weights will sit on this stand when needed. In order to make it easier to measure the length of the band throughout the experiment, it is helpful to selotape a meter ruler to the top of the stand so that '0'

2. ## An experiment to investigate and determine how rubber behaves when tension forces are applied ...

I do predict though that the extension will be proportional to the tension up to a point where all tensions are applied and the rubber band will suddenly snap. This is because the physical properties of a rubber band are those of which will eventually snap as the tension increases and if the load weighing it down is too much.

1. ## Stretching Springs/Hookes Law.

Beyond the elastic limit, the applied force separates the molecules to such an extent that they are unable to return to their original positions, and the material is permanently deformed or broken apart. From Encarta 99 The 2 opposite forces on the spring The 2 opposite forces are-: 1)

2. ## To investigate the stretching of an elastic band when it has some load on ...

I am going to find out how much the band stretches as I increase the load by 40g each time. It is much easier to maintain the extension rather than the force. Preliminary Results Table LOAD (g) LENGTH (cm) EXTENSION (cm)

At this stage the effect of force becomes less until the spring yields and separates (breaks). ~information from www.projectgcse.co.uk~ This information tells us how and why the cord will extend when we add weight onto the end in out investigation, and why I predict that the more weight added

* An electron that is free of an atom is defined as having 0 energy, therefore for a bound electron, as energy must be added to release it; its energy within the atom is negative. The lowest possible energy level an electron can occupy is called the ground state (n=1).
