Description Générale

The Unit for studying Hooke's Law "MELH" demonstrates the application of Hooke's Law and allows the visualization of the deformation of tension springs under load and the performance of oscillation experiments on a spring – mass system.

The MELH unit includes three springs with two different elastic moduli. They will be suspended from their upper end by hooks anchored to the frame.

Load will be applied to the lower end of the spring by hanging masses from it and the rules included in the unit will be used to read directly the deformation generated in the springs. Thus, the elastic modulus of each spring is obtained by applying Hooke's law.

The unit allows the performance of studies in series and in parallel by combining the springs provided.
