Graphical 3-point design Design a 4-bar mechanism that will flip that square box (side of the box = 2 units) upside down by grabbing it at points A and B as shown. (Your coupler pin joints are A and B. They must move though the positions A1B1, A2B2 and A3B3 as shown). Given the coupler point, your job is to design (locate) the fixed hinges O2 and O4. No need to design a dyad.  Type below the answer to this question:Will there be a defect in your design? If yes, will it be circuit or branch defect? Upload all your design work right after the exam: CAD or hand drawing with 3 positions of the boxes and the fixed hinges O2 and O4.

Analytical 2-point design Design a 4 bar mechanism that will lift the 0.5m x 0.5m square box from down position to the up position as shown. The coupler pin joints A and B should be at the top right and bottom right corners of this box.  No need to design a dyad.Coordinate origin is shown.  Paste the MATLAB code that clearly shows your givens and free choices and then calculates the location of O2 and O4. Also include a labelled CAD diagram that shows the location of coupler point P1, coupler hinges A1 and B1, the location of fixed hinges O2 and O4 and the configuration of the mechanism at the “2 points” You don’t have to, but if you design the fixed hinges O2 and O4 in the 2m by 2m region shown, you’ll get some extra credit. We are NOT designing a straight line mechanism. There are no constraints excepts the two positions of the box. (If you don’t know how to code, just write the steps and equations to be solved, and choices to be made, in a VERY sequential and systematic way)
