: A rotating shaft, supported at its end by rolling bearings is subjected to downward loads Fi=75KN and F:-15KN as shown. Also, a torque input of 3kN-m is applied at

position 1 (location of F1) and is removed at position 2 (location of F2) Determine the design life (number of revolutions) of each component (rotor, bearing “A" and bearing "B")and state which component is life limiting for the System. Shaft material is 1040 Cold-Drawn and Annealed Bearing "A" is Series-02 Deep-Groove Ball bearing Bearing "B" is Series-02 Cylindrical Roller bearing For rotor life, use ASME criteria and all K factors except K, Ks and Keare to be takenas 1.0 For both bearings, consider reliability of 99%, an application factor of 1.2, V=10, x=0.02, 0=1.459, b=1.483 and L=10 revolutions "Centrifugal" action, self-weight of the shaft, and shear forces on the shaft can be ignored) Determine the design life (number of revolutions) of each component (rotor, beating "A "and bearing "B")and state which component is life limiting for the
