The turning-moment diagram of a petrol engine is shown in Figure 5 below. The speed of the shaft must be maintained between 900 RPM and 1010 RPM. The values (in Joules) of the enclosed areas are collected in Table 1. Data Area [J] Torque a 470 b b 2040 Table 1 Figure 5 C a) Calculate the moment of inertia of a suitable flywheel. с 1890 d Shaft Angle d 320 b) Calculate the mass of the flywheel from a) if the radius of gyration is to be 0.25 m. (6 marks) (2 marks) c) Indicate the points on the graph where the rotation velocity of the shaft is at its minimum and at its maximum.
