The constant angular velocity of the two-cylinder engine crankshaft is ω = 200 rad/s counterclockwise. Determine the x and y components of the primary shaking force acting on the crankshaft bearing in terms of the crank angle θ. Then, determine the magnitudes and orientations of the correcting masses that must be added at the radial distance RC = 40 mm from the crankshaft axis.

Determine the answers when the reference line

(attached to crank 1) is specified at the crank angle

θ = 30◦, as shown on the figure to the right.
