Example Sentences
- "The balancing of the engine is unusual, with the rotating masses fully balanced and 40 per cent of the reciprocating masses statically balanced by lead weights in the coupled wheels; the reciprocrating balance weights are in the same phase on both sides of the engine. This system saves balance weight and reduces the wheel hammer-blow."
