With this briefcase, you can perform experiments in statics (Hooke's law), dynamics, and forced oscillations. Oscillations of a mass-spring system: - Verification of Hooke's law F= k.x to determine the stiffness of a spring - Dynamic study of a free or damped oscillator to determine the natural frequency and pseudo-frequency using a high-speed camera 2 ref 577017 or a wireless accelerometer ref 488060. Forced oscillations of a mass-spring system: An adjustable eccentric pulley allows driving the mass-spring system with a sinusoidal motion. A water-filled test tube provides fluid damping to assess its influence. Adjust the motor frequency, record the wave amplitude, then plot the curve A = f (exciter frequency). From this, you can deduce the resonance frequency, damping factor, and quality factor Q.
