Investigating the stretching of a material AIM: I am trying to find out what factors effect the stretching of a spring. Things, which might affect this, are: · Downward force applied to spring and elastic band. · Spring material. · Length of spring and elastic band. · Number of coils in spring. · Diameter of spring band material. · Cross sectional area of spring. I have chosen to look at the effect of the weight applied, as it is a continuous variation. PREDICTION: I predict the greater the force applied to the spring or elastic band, the further it will stretch. This is because extension is proportional to load and so if load increases so does extension and so stretching distance. I will also work out the extension which is done by taking away the extended length from the original length. In order to see if my prediction was correct, I will use Hooke's Law. (-Robert Hooke (1635-1703),...
