The device is delivered complete and allows the static and dynamic studies of springs: Hooke's law, free and forced oscillations, damping, etc.

Composition:

• 1 box with step engine, its control and its power supply (mains unit), display of the frequency of rotation
  
• 1 eccentric pulley connected to the step engine
  
• 1 integral stem with the case
  
• 1 graduated rule with central zero, mounted on a support that can slide on the stem
  
• 1 spring
  
• 1 rod serving as both a support for the mass and a guide for the spring
  
• 1 string connecting the eccentric pulley to the spring
  
• 3 masses of 50 g
  
• 3 plastic washers of different diameters for the study of friction
  
• 1 specimen to study the influence of a fluid damping on the oscillation amplitude
  Feasible studies with the device:
  
• Statics study: verification of Hooke's law
  
• Dynamics study: measuring the inherent period of a mass / spring system
  
• Study of forced oscillations: influence of the frequency of the exciter on the phase of the resonator
  Technical characteristics:
  
• Display: Red LED 3 digits
  
• Power supply: 230 V/50Hz
