What is damped free vibration?

Damped vibration occurs when the energy of a vibrating system is gradually dissipated by friction and other resistances, the vibrations are said to be damped. The vibrations gradually reduce or change in frequency or intensity or cease and the system rests in its equilibrium position.

How to Calculate Amplitude Reduction Factor?

Amplitude Reduction Factor calculator uses Amplitude Reduction Factor = e^(Frequency Constant for Calculation*Time Period) to calculate the Amplitude Reduction Factor, Amplitude Reduction Factor formula is defined as a measure of the reduction in amplitude of a vibrating system due to damping, providing a quantitative representation of the energy loss in a free damped vibration, which is essential in understanding the behavior of oscillating systems in various fields such as physics and engineering. Amplitude Reduction Factor is denoted by A_r symbol.
