3. PIN-IN-SLOT THREE-BAR MECHANISM. Link 1: fixed, horizontal, R = 10 in., endpoints A & C. A is to the left of C. Link 2: moving, endpoints A & B,

R = 3 in., Point B is a pin, inserted into the slot in Link 3, 0, = 105°, w2 = 10 deg/s ccw Link 3: moving, long straight slotted link, with one end pinned to point C on the ground with a revolute joint (A) (4 points) Draw the position vector loop(s) for this mechanism. Write the corresponding vector equation(s). (B) (4 points) Link 2 is the input link. Identify and count the remaining unknowns.Identify any constraints and which unknowns they relate. Count the total number of unknowns and the total number of available equations. Mark your vector loop equation(s) in part (B) with the appropriate known/unknown notation above each term. (eg. V?) (C) (10 points) Link 2 rotates 30 degrees cw. Draw and report the absolute displacement vector for point B. Use any method you wish to find the values. (X) (bonus +5 points) For Part (C), find and report how far the pin travelled along the slot.
