Amass is connected by means of a spring to an elastic support. the static deflection due to the weirhs of this mass is so mm. the support is oscillated with simple hamonic motion at 2.0 hz and amplitude 10 ms. determine the amplitude of vibration of the mass if the damping is net nie. the mass is now damped in oil bath which cyerts a yesistance proportional to velocity, and the spring anchorage 13 oscillated as before. it is observed that the amplitude of vibration of the mass is now cne-fifth of its previous value. find the damping ratio, the phase angle and the relative amplitude between mass and support.
