Hooke’s law (TM 400)

elastic behaviour of tension springs under load



  • 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 400demonstrates 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.
