0.8m. [Assumptions: No friction losses, no bending in shafts and no shock loading occurs] Turbine Main shaft Gear box Generakor Driveshaft Coupling Fig Q2 Determine, assuming a safety factor of 1.2: (a) the minimum diameters of the main and drive shafts respectively, ensuring that the angle of twist of the driveshaft cannot exceed 3 degrees: (b) the minimum number of M8 bolts required for the coupling on the driveshaft, if a clearance of 2x M8 bolt diameters is specified between the shaft and bolt hole edge. (c) what design improvement could be made to the coupling referred to in (b) to reduce the number of M8 bolts to 5.

The 12B series chain was chosen to deliver 12 kW of power from the electric motor at 1400 rpm. The transmission ratio is 2. What is the diameter of the pitch driving circle and diven sprocket?

A rigid coupling with 30 inches of bolt circle diameter transmits a torque of 18,000 lb-in. The coupling material has a yield strength of 90,000 psi.  The coupling is fastened by six bolts.  Assume design factor of  N=3 Calculate the diameter of each bolt.
