<p><b>Engine balance</b> refers to how the inertial forces produced by moving parts in an <a href="page.php?w=internal_combustion_engine">internal combustion engine</a> or <a href="page.php?w=steam_engine">steam engine</a> are neutralised with counterweights and <a href="page.php?w=Balance_shaft">balance shafts</a>, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while forces at twice crankshaft speed (second-order forces) can become</p><p>
