6. Let the overhang shaft shown has a span of 50 in, and supp reaction R2...
augue application? 6-10 A rotating shaft of 25-mm diameter is simply supported by bearing reaction forces R and R2. The shaft is loaded with a transverse load of 13 kN as shown in the figure. The shaft is made from AISI 1045 hot-rolled steel. The surface has been machined. Determine (a) the minimum static factor of safety based on yielding. (b) the endurance limit, adjusted as necessary with Marin factors. (c) the minimum fatigue factor of safety based on achieving...
2.The shaft shown in the figure is driven by a gear at the right keyways, drive a fan at eh left keyways, and supported by two deep grove ball bearings. The shaft is made of AISI 1020 cold- drawn steel. At steady state speed, the gear transmits a radial load of 230 Ibf and a tangential load of 633 Ibf at pitch diameter of 8 inch. Determine fatigue factor of safety at any potentially critical locations using the DE-Gerber failure...
