A flange bolt coupling is used to connect a solid shaft 90 mm in diameter to a hollow shaft 100 mm in outside diameter and 90 mm in inside diameter. If the shearing stress is 55 MPa, how many 10 mm bolts must be used on a 225 mm diameter bolt circle so that the coupling will be as strong as the weaker shaft? (Round up to whole number)

Problem 5 only, solve carefully, include the units in every step and draw the diagram. Thanks! A hollow shaft transmits 10 kW and running at 650 rpm with a shearing stress of 55 Mpa. The outside diameter is 1.2times that of the inside diameter. Find the inside and outside diameters in mm.
Please solve, include the diagrams, and do not copy from other bartleby answers. Handwritten solution is more preferred than typed. A flanged bolt coupling connects two shafts. The bolt circle diameter is 250 mm in which there are 12 bolts. The allowable shear stress is 56 MPa in the shafts and 22 MPa in the bolts. One shaft is hollow with outside diameter of 100 mm, while the other one is solid of diameter 50 mm. Determine the ratio of the outside and inside diameter of the hollow shaft and the bolt diameter so that both shafts and the flanged bolt coupling are having the same strength in torsion.
