Determine the location and the magnitude (kg.mm) of the mass.

Transcript: The shaft shown in the figure is rotating with a constant speed of (300/n) rpm. The three masses are connected to the shaft and rotate with it, causing an unbalance. The dynamic bearing reaction force at point B is measured asŘ= 0.21 +0.11, Newton. a) Determine the magnitude (Newton) and location of the dynamic bearing reaction force at point A. b) Determine the location and the magnitude (kg.mm) of the mass corrections to be added in the planes D; and Dy in order to achieve dynamic balance.
