hi to all lately we have treated the flexional oscillations ..in particular the model of jeffcott ... I must say that I have some difficulty interpreting the motion of the rotor. First of all, the professor has subdivided this motion conceptually in two motions: that of whirling (the motion of the center of the rotor around the axis of rotation) and the motion of wobbling (mote of the axis of the rotor around the axis of rotation). ..on the book however it is written that the whirling motion is the motion of the "center" of the disk (and in a figure refers to the geometric center)...now since the geometric center and mass center of the system do not coincide (for the presence of the imbalance) I am a little confused... more than the motion d wobbling makes to the axis of the rotor a devour surface with a summit in the baricenter himself .
thanks in advance for the answers :redface:
