Answer rating: 100% (QA)
Logarithmic decrement is a parameter used to quantify the rate at which the amplitude of oscillations in a system or structure decreases over successive cycles It is defined as the natural logarithm of the ratio of any two successive maxima or minima of a damped oscillatory system Mathematically the logarithmic decrement is given by the formula lnAn An1 Where An is the amplitude of the nth oscillation ...View the full answer
