TM 400 Hooke’s law
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.
TM 400 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.
