Problem 2: Use vector loop equation to find (a) the angular acceleration of link 3 and linear acceleration of the slider d¨ and (b) accelerations of points A and B of the S-C mechanism given in Problem 2 of HW#7. Use ω2​=10rad/s and α2​= 3rad/s2. Use the results of Prob. 2 of HW#7 and solve the problem for the open solution when d is positive (position shown below). All dimensions are in mm.
