Question
2. Two shafts, one solid the other one hollow, are connected end to end by means of a coupling in which there are 8 screws on the pitch diameter D = 250 mm. The solid shaft has diameter d = 50 mm and transfers the power P = 500 kW at 75 rev/s. The external diameter of the hollow shaft is dex = 75 mm. %3D Note: All parts of the system must be equally strong, and able to transfer the required power Calculate: (a) The internal diameter d; of the hollow shaft (b) The diameter of the bolts d, connecting the two shafts (c) If the hollow shaft has to be replaced by a rectangular hollow cross-section with outer dimensions b xh and uniform wall thickness of 4 mm. Calculate the values b, h while following the request to keep h = 2b
