A rigid plate of width 2 m and height 0.25m is suspended by light rods, as shown in Figure 2. The length of the rods AB and CD are 1

m and 2 m, respectively. The pin-joints at A, B, C and Dc an be considered frictionless. The angular velocity o of the rod AB is constant and has the value of 2 rad/s in the counterclockwise direction. Using the coordinate system shown in Figure 2, determine the angular velocities of the plate and rod CD at the instant shown.
