At the instant when OP is vertical and AP is horizontal, the link OD is rotating counter clockwise at a constant rate w=7rad/s. Pin P on link OD slides in the slot BC of link ABC which is hinged at A, and causes a clockwise rotation of the link ABC. The magnitude of angular velocity of link ABC for this instant is _____rad/s (rounded off to 2 decimal places).
