  LOB = 230 mm, LBC = 280 mm, LCA = 300 mm, dOB = 42 mm, dBC = 48 mm, dCA = 40 mm   The shaft (OA) is machined from 1045 cold-drawn steel (Sy = 530 MPa, Sut = 630 MPa) to the dimensions provided. The shaft rotates at constant speed of 1800 rpm and is supported by bearings at O and C. The belt tensions on pulleys A and B result in a constant torque on the shaft of 250 Nm and a completely reversing bending moment at critical point C of 500 Nm. The transition between diameters at point C has a fillet with a 2-mm radius.
