1) for the given position of the windshield wiper shown below, calculate the angular velocities and accelerations of the both wipers, if the angular velocity of the input link, ac, is 1 rad/sec. ac=10cm, cd=40cm, bd=25cm, be=15cm, ef=80cm, fg=13cm, angle between the left wiper and the be is 20 degre
