11.45 Determine the first critical speed by the Dunkerley and Rayleigh methods for the steel shaft shown in sketch i. Neglect the shaft mass. The area moment of inertia is I = 7r4/4, where r = shaft radius. The method of su- perposition may be used with the following given: P 8 GET (GE"] [ - (x – a)3 br3 7 xb (12 – 62) 2 Ans. NR = 765 rpm, ND = 783 rpm. 50 kg 35 kg 50-mmeliam |--50 mm -1000 mm -750 mm Sketch i, for Problem 11.45
