A two-cylinder locomotive has the following specification:
Reciprocating mass per cylinder = 306 kg, Crank Radius = 300 mm, Angle between cranks = 90°, Driving wheel
diameter = 1800 mm, Distance between cylinder centers = 650 mm, Distance between the driving wheel planes =
1550 mm.
Determine:
(i) The fraction of reciprocating masses to be balanced, if the hammer blow is not exceed 46 kN at 96.5 km/hr,
(ii) The variation in tractive effort,
(iii) The magnitude of swaying couple.
