Example 11.7. A single cylinder reciprocating engine has speed of 300 r.p.m., stroke 300 mm, mass of reciprocating parts 60 kg, mass of revolving parts at 150 mm radius, 44.4 kg. If two-third of the reciprocat- ing parts and all the revolving parts are to be balanced, find : (i) The balance mass required at a radius of 480 mm, and (ii) The residual unbalanced force when the crank has rotated 60° from top dead centre.
