A coupling joins two shafts of 15 mm diameter (D = 15), transmitting torque T that varies f 100 to 50 N-m. The 4 bolts on the flanges are located at radius R = 30 mm and are tightened a tensile pre-stress of 200 MPa so that there is no slipping between the flanges. The effectiv (load bearing) diameter of the bolts, d, is 5 mm. Determine the safety factor for the coupling 99% reliability. The materials are machined out of steel with Sut = 1500 MPa and endurance strength Se=260 MPa. D d
