An inside cylinder locomotive has its cylinder centre lines 0.70 m apart and has a stroke of 0.60 m. The rotating mass per cylinder is similar to 150 Kg. and the reciprocating mass per cylinder is similar to 180 Kg. The wheel centre lines are 1.5 m apart.

The whole of the rotating and 2/3 of the reciprocating masses are to be equal by masses placed at a radius of 0.6 m. Determine the magnitude and direction of the balancing masses. Evaluate the fluctuation in rail presume under one wheel, variation of tractive force and the swaying couple at speed of 300 r.p.m.
