To investigate the factors which will effect the stretching of a Helical Spring when put under a load. Aim: To investigate and analyse the factors which will effect the stretching of a Helical Spring when put under a load of weights. Theory: Things, which might affect this, are: · Downward force applied to the spring. · Spring material. · Length of spring. · No. of coils in spring. · Diameter of spring material. · Cross sectional area of spring. However, most of these do not come into play, apart from weight, as we are using the same type of weights. Hooke's Law: * Hooke's law states that the extension of a spring (or other stretch object) is directly proportional to the force acting on it. * This law is only true if the elastic limit of the object has not been reached. * If the elastic limit has been reached the object will not return to its original...
