Sir pl. Question. The logrithmic damping decrement of oscillation is 0.2. cal the percentage change in amplitude of oscillation after one complete cycle. Thanks

[@dontknow-u8n]

vibrating system is defined by the following parameters m=3kg, K=100N/m, C=3N-sec/m. Determine (ⅰ) Damping factor (ii) Natural frequency of damped vibration (in) Logarithmic decrement (iv) Ratio of two consecutive amplitude and (v) Number of cycles after which the original amplitude is reduced to 20 percent.
