A flange coupling is to connect two 57 mm shafts. The hubs of the coupling are each 111 mm in diameter and 92mm thick and the flange web are 19 mm thick. Six 16 mm bolts in a 165 mm diameter circle connect the flange.The keyway is 6 mm shorter than the hub’s thickness and key is 14 mm x 14 mm. Coupling is to transmit 45 KW at160 rpm. For all parts, yield point value in shear is one – half the yield value which is 448 MPa. Calculate the forceon the shaft
