A flanged bolt coupling is used to connect a solid shaft 110 mm in diameter to a hollow shaft 100 mm in outside diameter and 90 mm in inside diameter. If the allowable shearing stress in the shafts and in the bolts is 53 MPa, how many 15 mm-diameter steel bolts must be used on a 400 mm-diameter bolt circle so that the coupling will be as strong as the weaker shaft? This is an exception to our two decimal rule -- so our answer here must be rounded to the NEXT whole number.
