What is logarithmic decrement?
A measure of the mechanical damping. The logarithmic decrement is measured dynamically using a torsion pendulum, vibrating reed, or some other free vibration instrument, and is calculated from the natural logarithm of the ratio of the amplitudes of any two oscillations. Its formulation is: whereAi = amplitude of the ith oscillationA(i+n) = amplitude of the oscillation n vibrations after the ith oscillation.
What are some synonyms for the word decrease?
There are many synonyms for the word decrease, among which are: diminish, curtail, wane, lessen, decline, dwindle, reduction, abate, decrement, subside, lower, declension or contraction.
What is an algorithm for subtracting integers?
One way to do it might be like this:Get / store the integer to be subtracted from, and the integer to subtract-we'll call them A and B.Decrement A and B by 1 each.If B = 0, stop. A now contains the result.If B ≠ 0, decrement A and B by one again.Repeat from step 3.
How do you find the loss factor in hysteretic damping?
Loss factor is best obtained by dynamically loading (extensional, torsional etc.) a specimen of the material and plotting the hysteresis curve in stress-vs strain plane. If the total area under the hysteresis loop is D, the loss factor is computed from the following formula Loss factor=D/(2*pi*max stress* max strain) For lightly damped materials, loss factor is just twice the daming factor 'zeta' which obtained either by log-decrement method or half-power bandwidth method.

Does mean mean average?
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.
