100 mmj 12 A line shaft ABCD, 9 metres long, has four pulleys A, B, C and D at equal distance apart. Power of 45 kW is being supplied to the shaft through the pulley C while the power is being taken off equally from the pulleys A, B and D. The shaft runs at 630 r.p.m. Calculate the most economical diameters for the various portions of the shaft so that the shear stress does not exceed 55 MPa. If the shear modulus is 85 GPa, determine the twist of the pulley D with respect to the pulley A. [Ans. 28 mm, 36 mm, 28 mm ; 0.0985°]

1) A stepped steel shaft, shown below, is used in a spur gear reducer. The shaft is subjected to a constant axial stress (A=40 MPa), a constant bending moment that results in a variable stress (M=60 MPa) due to loads by bearings and gears, and a steady torque (T-80 MPa). However, these stress values do not take into account stress concentration factors. The shaft has a D=45 mm, d=30 mm, and r=6 mm, resulting in kr,bend=1.34, Kr,axial=1.48, and kf,tor 1.2. The shaft is made of steel with S₁=1006 MPa, S,=648 MPa, and H₂=229. The size of the shaft results in a gradient factor of CG=0.9. The shaft has a fine-ground finish. A 90% reliability is required. Verify the stress concentration factors are correct for this shaft geometry. Calculate the safety factor relative to infinite life (105 cycles). If the safety factor is less than one (i.e., shaft fails), find the number of cycles to failure. (60) M
