A Hackworth radial mechanism is shown in Figure Q1. Link 2 is pinned to the frame at O. Link 4 has a linear velocity of 400 mm/s. Link 2 has an angular acceleration of 2 rad/s? (a) Construct the velocity and acceleration diagrams for the mechanism. (15 marks) (b) (5 marks) Determine the magnitude and direction of: (i) Linear velocity of link 8 and angular velocity of link 2 Linear acceleration of link 6 and angular acceleration of link 7 (iii) Acceleration of joint B The position of the mechanism, direction of the velocity of link 4 and the direction of the angular acceleration of link 2 are obtained from the even/odd of the first three digits of your assigned number code.
