At the given instant as shown in Figure Q1(a), the rod AB rotates at 2 rad/s
anticlockwise. Knowing that AB is 300 mm long, BC is 500 mm long and CD is
400 mm long.

Determine the angular velocity for rod BCD, the velocity at point D and explain with calculation on ways to increase the velocity of Block C.
