Forced harmonic vibration
WebOct 25, 2015 · In the simplest of terms, Harmonic Vibration is when a mechanical object vibrates at harmonic frequencies. There’s two different kinds of vibration; free and forced. Free vibrations are those of which you cause and let happen. They are usually desirable, like that of a tuning fork. WebSep 12, 2024 · Figure 15.6. 4: The position versus time for three systems consisting of a mass and a spring in a viscous fluid. (a) If the damping is small (b < 4 m k ), the mass oscillates, slowly losing amplitude as the energy is dissipated by the non-conservative force (s). The limiting case is (b) where the damping is (b = 4 m k ).
