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. · Spring material. · Length of spring. · No. of coils in spring. · Diameter of spring material. · Cross sectional area of spring. I have chosen to look at the effect of the weight applied, as it is a continuous variation. I predict that the greater the weight applied to the spring, the further the spring will stretch. This is because extension is proportional to load and so if load increases so does extension and so stretching distance. Extension = New length - Original length To see if my prediction is correct I will experiment, and obtain results using Hookes Law. He found that extension is proportional to the downward force acting on the spring. Hookes Law F=ke F = Force in Newtons k = Spring constant e = Extension in Meters My method of experimentation...
