In under damped vibrating system, if x 1 and x 2 are the successive values of the
amplitude on the same side of the mean position, then the logarithmic decrement is equal to
A x 1 /x 2
B log (x 1 /x 2 )
C loge (x 1 /x 2 )
D log (x 1 .x 2 )
amplitude on the same side of the mean position, then the logarithmic decrement is equal to
A x 1 /x 2
B log (x 1 /x 2 )
C loge (x 1 /x 2 )
D log (x 1 .x 2 )
