Description
The primary function of this apparatus is to study Hook’s Law and simple harmonic motion by studying the behavior of a mass on a spring. Your goal will be to extract a measure of the stiffness of one particular spring. Hook’s Law states that the extension of the spring is directly proportion with the applied load within the elastic limit of body.
The apparatus consists of a helical spring which is hanging along a scale that is fitted on a metallic rod. The other end of the spring is free. A hanger and pointer are attached to its free end.
Hooke’s Law describes the elastic behaviour of components where deformation is proportional to the load acting upon them. This behaviour is typical for metals under light loads.
The apparatus of Hooke’s law shows the deformation of tension springs under load. For this purpose, a spring is suspended from a stand and loaded down by a weight. The elongation is read-off directly from a scale. As a linear relationship is shown between the active force and the elongation of the spring, Hooke’s Law can be applied.
