and for element number 8 to 10, where elemental length is l3 = 0.0382 m.
The above damping is known as the proportional damping. Next, by attaching trial mass to the balancing planes, one by one, on both balancing planes, it is attempted to balance the first two modes vibration of the rotor system by the influence coefficient method.
