Arm ACB rotates clockwise about the fixed point C, which is at the midpoint between points A and B, with constant angular speed wo. Two friction disks D and E are pinned at their centers to arm ACB as shown. Knowing that the disks roll without slipping at all contact surfaces, determine the angular velocities of disks D and E as functions of wo. Also, determine the accelerations of points P and Q, which are the points on disks D and E, respectively, that are in contact with one another at this instant.
