) العنوان |7. A shaft carries three pulleys A, B and C, the pulleys B and C being 4 ft. and 7 ft. from A. The pulleys are out-of-balance to the extent of 3, 5 and 4 lb.in. respectively and are keyed to the shaft so as to give static balance. Find the relative angular positions of the radii which define the unbalance. If the shaft is supported in bearings 6 ft. apart, find the dynamic load on each bearing when the shaft makes 300 r.p.m. (I. Mech. E.) (Ans.: Relative to A, B, 126° 52'; C, 270°; 7-23 lb.
