A 40kg fan has a rotation unbalance of magnitude of 0.05kgm tge fan is mounted on a beam which is specially treated to have a viscous damping by the variation of the speed of the fan the amplitude of the vibration varies too. What is the fab's steady state amplitude when it operates at 1000r/min? Given E=200GPa I=1.3*10^-6 m L= 1.2m Damping ratio =0.0617
