EMAE 181 – Dynamics Homework #7 – Vector Chain Derivatives Due Friday 2 nd week of class The disk rolls without slipping on the surface. At the instant shown, the disk has an angular velocity of 20 rad/s CW and an angular acceleration of 5 rad/s 2 CCW. Fill out the chart on the following page similar to how we did in class on Tuesday. Determine the velocity and acceleration of pin A with respect to the slotted member BC and the angular velocity and angular acceleration of arm BC . Let r = 0.2m. Neglect the distance from the center of pin A to the edge of the disk.
