Background Information. This investigation will be based on Hooke's law. Robert Hooke was born in 1635, he was well known for his studies of elasticity. Hooke's most important discovery is the correct formulation of the theory of elasticity. An object is said to behave elastically when equal increases in the force applied to it produce equal changes in length. If a graph is drawn to show the average extension plotted against the load in Newtons a positive straight-line gradient should be seen, as extension is directly proportional to the load. The ratio between the load and the extension gives us a constant, this constant is called the spring or force constant. Hooke's law states: F = kx k = the constant of proportionality (the spring constant). x = the spring extension (e.g. x metres) Or: The deformation of a material is proportional to the force applied to it provided the elastic limit is not exceeded. The...
