EXAMPLE: The masses of the reciprocating parts of a four-cylinder engine are R. 300, 450 and R kg and the centre lines of the cylinders are 0.6, 1.2 and 0.9 m apart respectively. If the angle between the two inner cranks is 80°, find the magnitudes of R, and R. and the angular positions of the corresponding cranks for the primary forces and couples to balance. If the crank radius is 0.3 m and the connecting rod 1,5 m long, find the unbalanced secondary force at a speed of 120 rev/min. w
