2 The figure shows a mechanism consisting of a slider, attached to link 3 at B through a revolute joint. Link 3 is attached to link 2 through a revolute joint at A. Link 2 is attached to the inertial frame through a revolute joint at O. Link 2 is 200 mm long and link 3 is 300 mm long. B is constrained to move in a slot angled at 40° to the horizontal. Initially, B is horizontally in line with O and is at rest. At this point, the distance between O and B is 250 mm. B then accelerates at a rate proportional to the velocity according to the equation a-kv where k 10 s1 After the slider has moved a distance of 100 mm determine its velocity At this point determine the velocity of A and the angular velocities of links 2 and 3 using: 1. Graphic methods (choose a scale such that the length of the velocity vector for B is 5 cm) 2. Vector Methods 3. Instantaneous centre of zero rotation At this point determine the acceleration of A and the angular accelerations of links 2 and 3 using- 4. Graphic methods (choose a scale such that the length of the acceleration vector for B is 5 cm) Vector Methods 5. 2 The figure shows a mechanism consisting of a slider, attached to link 3 at B through a revolute joint.
