The cranks of a three-cylinder single-acting engine are set equally at 120°. The (10) engine speed is 540 rpm. The turning moment diagram for each cylinder is a triangle for the power stroke with a maximum torque of 100 N.m at 60° after dead centre of the corresponding crank. On the return stroke, the torque is sensibly zero. Determine the a) power developed b) coefficient of fluctuation of speed if the flywheel has a mass of 7.5 kg with a radius of gyration of 65 mm. c) coefficient of fluctuation of energy d) maximum angular acceleration of the flywheel The cranks of a three-cylinder single-acting engine are set equally at 120°.
