Thanks All the best
Question-4 [10 Marks] The turning moment diagram for a multi cylinder IC engine is drawn to the following scales 1 cm = 15° crank angle 1 cm = 3 k Nm During one revolution of the crank the areas with reference to the mean torque line are 3.52, (-) 3.77, 3.62, (-) 4.35, 4.40 and (-) 3.42 cm². Draw the turning moment diagram and determine mass moment of inertia to keep the fluctuation of mean speed within – 3% with reference to mean speed. Engine speed is 200 rpm.
