The following data apply to an outside cylinder uncoupled locomotive: Mass of rotating parts per cylinder = 250 kg; mass of reciprocating parts per cylinder = 200 kg; angle between cranks = 90°; crank radius = 0.3 m; cylinder centres = 2 m; radius of balance masses = 0.75 m; wheel centres = 1.45 m. If the whole of the rotating and two-thirds of the reciprocating parts are to be balanced in planes of the driving wheels, find the magnitude of swaying couple at 300 rpm. Select one: A. ±33.4 kNm B. ±51.2 kNm C. ±37.5 kNm D. ±27.9 kNm
