Figure 41: Experimental forced vibration response (acceleration) of mass 4 due to a disk operating
with an unbalance mass m = 0.045 Kg with an eccentricity radius e = 0.040 m at 5 rotational
speeds: (a) 225 rpm (3,75 Hz); (b) 495 rpm (8,25 Hz); (c) 615 rpm (10,25 Hz); (d) 900 rpm
(15,00 Hz) and (e) 975 rpm (16,25 Hz).
