The engine in a small plane is specified to have a torque of 150 Nm. This engine drives a 2m long propeller that has a mass of 40,000 g. M=40,000g The torque from the engine rotates the L=2.0m propeller Axis (a) Calculate the moment of inertia of the propeller. You can assume it is thin rod rotating about its centre, I = : MLZ 12 7. (1 Mark.) (b) Calculate the angular acceleration caused by the 150 Nm torque? (2 Marks) (c) How long does it take the propeller to reach 500rpm? (2 Marks)
