1. The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by a gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the driver gear acts at a pressure angle of 20 degree. The shaft transmits a torque to point A of TA =340 N.m. The shaft is machined from steel with S,=420 MPa, Km2.5, S=134MPA and N=2. Draw shear and bending diagrams and calculate diameter of shaft. 250 mm 100 mm
