Two shafts of diameter 30mm each are connected by a flange coupling. Six bolts, each of diameter 8mm, are used on a pitch circle of diameter 90mm. If the allowable shear stress of the bolt material is 80MPa, what is the torque – transmitting capacity of the bolts to the nearest 10units?
(a) 780 N-m (b) 950 N-m
(c) 1090 N-m (d) 1250 N-m
