2. A flange coupling is to connect two 57 mm shafts. The hubs of the coupling are each 111 mm in diameter and 92 mm thick and this flange webs are 19 mm thick. Six mm bolts in a 165 mm diameter circle connect the flanges. The keyway is 6 mm shorter than the hub's thickness and the key is 14 mm x 14 mm. Coupling is to transmit 45 kw at 160 rpm. For all parts, yield point in tension and compression which is 448 MPa. Find the following stress and factors of safety based on yield point. a) Shear in key b) Bearing in key c) Shear in bolts d) Bearing stress in bolt e) Shear stress in flange at hub f) Torsional stress in the shaft
