The mode shapes of an un-damped two degrees of freedom system are {1 0.5}T and {1 -0.675}T The corresponding natural frequencies are 0.45 Hz and 1.2471 Hz. The maximum amplitude (in mm) of vibration of the first degree of freedom due to an initial displacement of {2 1}T (in mm) and zero initial velocities is
Correct : 0.008 to 0.012
