The crankshaft of the three-cylinder engine (Fig.

P15.26, next page) is rotating with a constant angular velocity ω = 50kˆ rad/s. Determine the x and y components of the primary shaking force, the magnitude(s) of the correcting force (or forces)

created by the correcting mass (or masses), and the orientation(s) of the correcting force (or forces).

Determine the answers when the reference line

(attached to crank 1) is specified at crank angle

θ = 0◦.
