Question 4 A thin disk is supported on spring-mounted bearings with vibration pickup and strobotac, as shown in Fig. Running at 800 rpm ccw, the original disk indicates a maximum amplitude of 2.90 mm at 45° cw from a reference mark on the disk o Next a trial weight of 3.0 oz is added at the rim in a position 91°cw from the reference mark and run at the same speed. If now the new unbalance is 6.0 mm at 80° cw from the reference mark, determine the position and weight necessary to balance the original disk o. رقم الاستار 459 30 35 Ret
