Question

he turning moment diagram for a petrol engine is drawn to the following scales:
Turning moment, 1 = 5 ;
Crank angle, 1 = 1°.
The turning moment diagram repeats itself at every half revolution of the engine and the areas above
and below the mean turning moment line, taken in order are 295, −685, 40, −340, 960, −270 2
.
Determine the mass of diameter flywheel rim when the coefficient of fluctuation of speed is
0.3% and the engine runs at 1800 .

Answer 1

Answer:

Given : m = 36 kg ; k = 150 mm = 0.15 m ; N = 1800 r.p.m. or ω = 2 π × 1800/60 = 188.52 rad /s Read more on Sarthaks.com - https://www.sarthaks.com/809480/the-turning-moment-diagram-for-a-petrol-engine-is-drawn-to-the-following-scales
