A two cylinder uncoupled locomotive has inside cylinders 0.6 m apart. The radius of each crank is 300 mm and are at right angles. The revolving mass per cylinder is 250 kg and the reciprocating mass per cylinder is 300 kg.
The whole of the revolving mass and two-third of reciprocating masses are to be balanced and the balance masses are placed in the planes of rotation of the driving wheels at a radius of 0.8 m. The driving wheels are 2 m in diameter and 1.5 m apart.
If the speed of the engine is 80 kmph, find the hammer blow, maximum variation in tractive effort and maximum swaying couple. Find the maximum velocity of the locomotive if maximum allowable dead load on each wheel is limited to 40kN
