A hydrofoil boat has an AISI 1020 Hot Rolled steel propeller shaft that is 100 ft. long. It is connected to an in-line diesel engine that delivers a maximum power of 2500 hp and causes the shaft to rotate at 1700 rpm. If the outer diameter of the shaft is 8in. and the wall thickness is 3/8" determine.
a) the maximum shear stress in the shaft.
b) the angle of twist in the shaft
c) the design factor (factor of safety) assuming repeated torsion .Is it reasonable or not and why?
