![]() ![]() The motion of the ground causes the pendulum to sway, reducing the risk of structural damage. In other words, they protect buildings from earthquakes. However, there are other examples of oscillators that you may encounter some of them are listed below:įriction pendulums, which are used as seismic isolators. ![]() After all, not many people own a classical standing clock and even fewer use devices such as a seismometer or a gravitometer. How to find the damping coefficient? It is an intrinsic property of the spring, usually found by measuring the amplitude decay rate and performing computations or deriving it from other properties.Īlthough the pendulum is the most common and straightforward example, it does not seem overly applicable to most of us - at least not initially. The system's damping factor determines how quickly the mechanical energy is dissipated and the object returns to rest. The oscillator keeps on moving forever, constantly exchanging its kinetic and potential energy (which you can read more about in the potential energy calculator). Undergoing simple harmonic motion - damping does not occur.Any less and it would be considered underdamped. The damping is just right and so is the minimum value to provide non-oscillatory motion. Critically damped - this case is similar to the overdamped one, but the object reaches its equilibrium faster.An example would be a pendulum submerged in a viscous liquid, such as honey. Overdamped - the object fails to complete even a single oscillation and its velocity approaches zero as it approaches the equilibrium (rest) position.This is the case when the damped harmonic oscillator (e.g., pendulum) is left on its own. Underdamped - damping is small enough to make the amplitude decrease with time.Hence there are four cases of oscillatory systems: ![]()
