Solid arm AB makes a regular circular motion about pin A, but because of the offset between the pins, slotted arm CD makes an eccentric motion.  Find the angular velocity  and acceleration of the slotted arm whenw_AB=0.deltadeltadelatdelta rad/s and a_AB=0.5rad/s². Although it looks like it in the picture, based on the angles and dimensions given, A is not vertically aligned with C.
