In Four-bar chaim ABCD, link Ad is fixed, and the crank AB rotayes clockwise at a constant speed of 10 radians per second .Length of the links are AB=60 mm;BC=CD=70 mm; DA=120 mm. The angle DAB=60 degrees and both B and C lie on the same side of AD 2.1 Draw the displacement diagram of the mechanism taking link AD as horizontal

2.2Use the vector diagram yo calculate angular velocities(magnitude and direction) of BC and CD, and

2.3 angular acceleration of BC and CD
