A three-cylinder single acting engine has its cranks set equally at 120° and it runs at 1200 r.p.m. The torque-crank angle diagram for each cycle is a triangle for the power stroke with a maximum torque of 90 N-m at 60" from dead center of corresponding crank. The torque on the return stroke is sensibly zero. Determine: • Power developed. • Coefficient of fluctuation of speed, if the mass of the flywheel is 6 kg and has a radius of gyration of 80 mm. • Coefficient of fluctuation of energy. Maximum angular acceleration of the flywheel.
