12 in. B 6 in. D 3 in. 3 in. 12 in. PROBLEM 15.67 Robert's linkage is named after Richard Robert (1789-1864) and can be used to draw a close approximation to a straight line by locating a pen at Point F. The distance AB is the same as BF, DF and DE. Knowing that the angular velocity of plate BDF is 2 rad/s counterclockwise when 0= 90°, determine (a) the angular velocities of bars AB and DE, (b) the velocity of Point F. When = 90°, determine (a) the angular velocity of bar DE (b) the velocity of Point F.

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
