A flanged bolt coupling consists of 20-mm aluminum bolts evenly spaced around a bolt circle 30 cm diameter and 12-mm steel bolts on a concentric bolt circle 20 cm in diameter. The allowable shearing stresses are 42 MPa in the aluminum and 62 MPa in the steel. What should be the minimum number of aluminum bolts if there are four steel bolts and the power applied is 760 kW at 600 rpm? Use Gal = 28 GPa and Gst = 83 GPa.
