This assignment pertains to the planar fourbar mechanism illustrated here. Link 1 is the ground link and includes points O2 and O4. Link 2 connects points O2 and A. Link 3 is a rigid body with moving pivots at points A and B, and Point P is another fixed point on Link 3. Link 4 connects points O4 and B. A 2-D Cartesian coordinate system is fixed to ground with its origin at O2. Can you solve all of it...

At time ? = 0 link OA of the mechanism shown below has an initial angular velocity of ??? = 9? ???/? and is at a position of ? = −30? . Suddenly, a brake is applied which provides a time-dependent deceleration of link OA of ??? = (−1 − ?)? ???/?2 . Use kinematic relationships to find expressions for the angular velocity of link OA (???(?)) as well as the angular position of point A (?(?)) on the link...
