The arrangement of cranks in a six-cylinder in-line engine is shown in the figure. The cylinders are separated by a distance a in the axial direction, and the angular positions of the cranks are given by a₁ = α = 0°, α₂ = α5 = 120°, and a3 = a4 = 240°. If the crank length, connecting-rod length, and the reciprocating mass of each cylinder are r, l, and m, respectively, find the primary and secondary unbalanced forces and moments with respect to the reference plane indicated in the figure.

Transcribed Image Text:The arrangement of cranks in a six-cylinder in-line engine is shown in the figure. The cylinders are
separated by a distance a in the axial direction, and the angular positions of the cranks are given by α₁ =
α6 = 0°, α₂ = α5 = 120°, and a3 = α4 = 240°. If the crank length, connecting-rod length, and the
reciprocating mass of each cylinder are r, I, and m, respectively, find the primary and secondary unbalanced
forces and moments with respect to the reference plane indicated in the figure.
