Balancing 425 Q.7 A twin cylinder V-engine has the cylinders set at an angle of 45°, with both pistons connected to the single crank, The crank radius is 62.5 mm and the connecting rods are 275 mm long. The reciprocating mass per line is 1.5 kg and the total rotating mass is equivalent to 2 kg at the crank radius. A balance mass fitted opposite to the crank, is equivalent to 2.25 kg at a radius of 87.5 mm. Determine for an engine speed of 1800 r.p.m.; the maximum and minimum values of the primary and secondary forces due to the inertia of reciprocating and rotating masses. [Ans. Primary forces : 3240 N (max.) and 1830 N (min.) Secondary forces : 1020 N(max.) and 470 N(min.)]
