Investigation to show how Elastic Bands Behave Under Load Prediction The aim of the investigation is to determine how elastic bands behave under load. Before I begin the investigation I will carry out a preliminary experiment into the behaviour of a spring, which I believe will not act in the same way as the elastic band. In the preliminary investigation a spring was put under load and the results were as follows: Load/g Length/cm Extension/cm 0 2.2 0 100 11.0 8.8 200 13.1 10.9 300 15.3 13.1 400 17.2 15.0 500 21.1 18.9 600 24.6 22.4 700 29.0 26.8 800 34.3 32.1 900 88.5 36.3 1000 42.0 39.8 1100 46.6 44.4 1200 1300 1400 From previous knowledge of Hooke's Law, which explains, extension is proportional to load until elastic limit is reached. The preliminary experiment with the spring shows, that they obey Hooke's Law up until the point of permanent deformation (elastic limit). I think that the thinner rubber band will have a bigger extension than the thicker band and the longer band will have bigger extension than the shorter band. I think the longer rubber band will have the biggest extension because...
