Physics Rubber Essay

Rubber is an elastic material, so when the force is removed; it returns to its original size and shape. Its structure is that, it’s a polymer as it has many long chains of this molecule (hydrocarbons). Rubber is used for many purposes including making tires, belts, hoses, furniture, rubbers and many more.  

The force-extension graph for rubber:

The force extension graph shows us that, the more force you apply to the material, the bigger the stretch/extension there will be. The blue line is indicating the stretch, and how we’re applying force to the material - it’s increasing. Whereas, the grey line is showing us the unstretch, so when we are removing the force individually. Notice, how this time, the line doesn’

The environmental problem is that the tyres made out of rubber are not biodegradable, so are very difficult to recycle and dispose of. They use up a lot of room, and also, if caught on fire, take a huge amount of energy and time to extinguish, releasing toxic gases into the atmosphere. However, this could be tweaked to be a benefit for the environment, as tires could be an energy source for the people. They could burn tires, reducing costs on energy, or maybe shredding the tyres and putting them on kids’ playgrounds ensuring it has a sustainable development.

Also, factories that produce rubber release many gases into the atmosphere, contributing to global warming and climate change, making the world a more hotter and dangerous place to live in.

Conclusion

This practical relates to my case study, as both these materials are polymers and have long chains. Also, I have talked about the force extension graphs, their trends and line of best fits, which I have also discussed in the practical. Because, we’re talking about the stress and strain of an polymer in the case study, it links in as we find the young modulus of an polymer in the practical and talk about how it shows the stiffness of an material, not an object etc.
