2. A flanged bolt coupling consists of seven 12-mm diameter bolts arranged on a bolt circle 300 mm in diameter, and five 12-mm diameter bolts on a concentric bolt circle 250 mm in diameter. Calculate the torque that can be applied if the allowable shearing stress in the bolt is 60 MPa. Answer: T = 10.66kN-m 3. Determine the number of 12-mm diameter bolts that must be used on the 250-mm bolt circle of the coupling mentioned in Problem 2 to increase the torque capacity to 12 kN-m.
