Question

A 40 kg fan has a rotating unbalance of 0.1 Kg-m. The fan is mounted on the beam( length of beam 1.2 m). the beam has been specially treated to add viscous damping. As the speed of the fan is varied, it is noted that its maximum steady state amplitude is 20.3 mm. what is the fan’s steady state amplitude when it operates at 1000 rpm. Take E = 200 GPa, I = 1.3 x 10-6 m4 , moe = 0.1 kg-m.
