The figure is like aschematic drawing of asolid counter shaft that supports two that belt Pullers each having ason weight. For each pulley, the belt gensions are parallel and the coefficient is friction between the belt and Pelley Ais dits. If a cold-drawn uns Glo 180 steel shast a vitorm diameter in material properties of allowable strength in shea, and in benders may be taken as 220 MPa and 440 MPa respectively. Determine the minimum Preferred size diameter in accordance to the ASME code usino km= 15 and Ke=10. Neglect the effect a mass and thickness of belts and mass of the shaft
