EM-101 | Mass Spring System Apparatus

To demonstrate the use of dimensional analysis to a fluids class. This demonstration uses a dimensional analysis to examine the relationship between frequency of oscillation of a spring and the mass supported by the spring. 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, demonstrates the application of Hooke’s law and shows the deformation of tension springs under load. For this purpose, a spring is suspended from a stand and loaded. 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.
