act your Instructor. The door shown (HC) has a hinge (pinned) at point H and links BC and AB, with AB pinned at point A and BC pinned at point C. A and BC together at point B. If the length of the horizontal link, BC, is Lac = 0.4 m and the length of HC is Lac 0.7 m, determine the angulas y instant shown. The angular velocity of HC is wH = 7 rad/s and 0 =25°. 1.25 rad/s 00 rad/s 07 rad/s 1.54 rad/s 2.95 rad/s
