3. For the offset crank-slider linkage in the following figure (a) derive the expression for the

angular velocity of link 3 and linear velocity of link 4 using analytic vector-based methods (not

complex number representation of vectors). [6 points] (b) derive the expression for the angular

acceleration of link 3 and linear acceleration of link 4 using analytic vector-based methods. [9

points] (c) Assuming that the link 2 at 45degrees in the global XY coordinate system, find the

acceleration of point A and B in the global.
