Question

If link AB of the four-bar linkage has a constant counterclockwise angular velocity of 53 rad/s during an interval which includes the instant represented, determine the angular acceleration of AO (positive if counterclockwise, negative if clockwise) and the acceleration of point D. 90 mm B WAB 190 mm 140 mm 140 mm Answers: CAO = Jrad/s2 ap li) m/s2

Answer 1

First we solved for the Acceleration equation terms, after that for angular acceleration at OA we solved for the same. For acceleration point we used terms in the acceleration equation and by following general procedure we find the given requirements
