At the instant shown die angular velocity of links BE and CF is 6 rad/s counterclockwise and is decreasing at the rate of 12 rad/s2 Knowing that the length of each link is 15 in. and neglecting the weight of the links, determine (a) the force P, (b) the corresponding force in each link. The weight of rod AD is 15 lb.
