A rotating shaft is made of AISI 1035 CD steel is subjected to an axial load of 710N
A rotating shaft is made of AISI 1035 CD steel is subjected to an axial load of 710N, a fluctuating torque load from 60 to 120 N.m, and a completely reversed bending moment of 160N.m. The shaft has a diameter of 30mm, and operates at T=250°C, and has a life reliability of 95%. Note that the fatigue stress-concentration factor for bending Kfb is 1.49 and that for torque Kft is 2.65..1. Draw the Yield (Langer) line 2. Modified Goodman line. 3. Calculate...

The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the drive gear acts at a pressure angle of 20". The shaft transmits a torque to point A of TA = 340 N.m. The shaft is machined from steel with Sy= 420 MPa and Sut = 560 MPa. The fatigue...
