A horizontal gas engine running at 210 rpm has a bore of 220 mm and a stroke of 440 mm. The connecting rod is 924 mm long and the reciprocating parts weight 20 kg. when the crank has turned through an angle of 300 from the inner dead center, the gas pressures on the Cover and the crank sides are 500 kN/m2 and 60 kN/m2 resp. Diameter of the piston is 40 mm. Determine i) turning moment on the crank shaft. ii) thrust on bearings iii) acceleration of the flywheel which has a mass of 8 kg and radius of gyration of 600 mm while the power of engine is 22 kW.
