The rotating shaft shown below is supported by self aligning bearings at A and D. The diameter of the shaft changes from D-1.5" to d-1.0" at the midpoint of the shaft. The radius of the fillet at the diameter change is r-0.2" and all surfaces are machined. The shaft is made of normalized 1020 steel having . 64.0 ksi and S, = 50.3 ksi . The shaft is loaded with 250-lb forces at B and C as shown to create...

QUESTION-3 Shaft shown in the figure is supported by A and C bearings. Bearing A has 4300 N radial and 1400 N axial force due to the tooth force of the gear wheel on the shaft. Only a radial force of 3100 N acts on bearing C. The shaft diameters are the same in the region where the A and C bearings are located and dA = dC = 35 mm The rotation speed of the spindle is...
