Bar OA has a counterclockwise angular velocity ω0 = 3.4 rad/s. Rod BC slides freely through the pivoted collar attached to OA. Determine the angular velocity ωBC of rod BC (positive if counterclockwise, negative if clockwise) and the velocity Vrel of collar A relative to rod BC (positive if moving from B to C, negative if it moves from C towards B).
