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.
