d the vertical shaking force would be WV2 gR sin 0 = 2900 sin A good counterbalance can be obtained by the addition of weightsformed by prolonging the crank-arm in single- or overhung-crankengines and prolonging both arms in double-crank arm engines.The product of the added weight and the distance… … Fig. 220. In general, rotating weights cannot be balanced by a singlerotating weight, as it is not practically possible to put the centerof gravity of the counterweight in the plane of revolution of thecenter of gravity of the unbalanced weights. For equilibriumit is essential that the moments of…
