(2) The turning moment diagram of an engine is simplified by the diagram shown in figure 2. Engine average speed is 1400 rpm. Find the following: a) Average output moment. b) Work done by the engine to change the speed from minimum to maximum. c) The total moment of inertia of the engine required to make the fluctuation coefficient 0.04. d) The maximum instantaneous speed of the engine. 160 140 120 100 80 60 40 20 -20 -40 0 45 90 135 180 225 270 315 360 405 450 495 540 585 630 675 720 Crank angle (degree) Output torque (N.m)
