(a) A solid driveshaft from a turboprop engine of circular cross section has a radius of 72mm. Due to the material properties of the shaft, the shear stress is limited to 80MPa and has a modulus of rigidity of 90GPa. (a) (b) (c) (d) Prop Gearbox Shaft Compressor Turbine Exhaust Combustion chamber Figure 5 Calculate the maximum torque that the shaft can transmit. If the length of the shaft is 0.8m, calculate the angle of twist of the shaft at maximum torque. The solid driveshaft is now replaced with a hollow driveshaft of the same material. The hollow shaft has the same outer diameter but has a wall thickness of 30mm. Calculate the maximum torque that can be transmitted by the hollow shaft. In the context of the answers calculated above, describe two advantages of using a hollow shaft over a solid shaft in the turboprop engine in figure 5.
