INVESTIGATING HOOKE'S LAW INTO THIN WIRES AIM To find out weather or not Hooke's Law applies to thin wires. THEORY This is an investigation into Hooke's Law and how it operates in relation to the thin wires we are going to be testing. the basic equation for Hooke's Law is F=KX. What this basically means is that the force is directly proportional to the extension. This is shown in Fig 1.1. In the darkly shaded area the material is elastic and thus the Law applies. However, if the external force is too strong, the material can become permanently deformed thus meaning that Hooke's Law on longer applies. This is represented in Fig 1.1 by the lightly shaded area. ================================================================ The elastic limit - also shown in Fig 1.1 - of a material is determined by the molecular structure of the material. The distance between molecules in a stress-free material depends on the balance...
