SMS-700
The spring-mass system is designed for observing the simple harmonic motion of the mass placed on the spring, measuring the period of sinusoidal movements and comparing them with the theory at the natural frequencies. It can be used to understand the forced vibration that an external force at a certain frequency is applied to the system. SMS-700 is an experimental device to measure motion patterns at natural frequencies and near natural frequencies and to understand what happens when the system is exactly in the natural frequency.
