1 The crank effort diagram for an engine is given by T(kgfm)= 7850+1500Sin2¢ where ¢ is the crank displacement. The crank has a mean speed of 100 rpm and the resisting toque is constant. Find (i) HP of the engine. (ii) The weight of the flywheel rim having a mean radius of 4m to limit the speed fluctuation to 2%. (iii) The angular acceleration when the crank is 30° from the dead centre.
