In a four bar mechanism ABCD, AD is the fixed link 120 mm long. Crank AB is 40 mm long. It rotates at an angular velocity of 10 rad/sec and had an angular acceleration (a)- 30 rad/sec² both clockwise. Link CD = 60 mm oscillates about D. BC and AD are of equal length. The angle DAB = 60°. The configuration diagram is given to you. Draw the velocity and acceleration diagrams and find: a. The linear velocity of C and D. b. The angular velocities of link BC and CD. c. The tangential acceleration of link BC and CD if the angular acceleration of link BC is 20 rad/sec² and the angular acceleration of link CD is 40 rad/sec². Note that: Link • The configuration diagram is given. • You need to draw the velocity diagram with suitable scale. Centripetal Acceleration Length of link (m) Velocity of Link (m/s) a.
