1. ME 115 Final Spring 2003 Problem 2 By Luke Saxelby

2. In order to build this model I started by drawing all of the rods to the proper size and orientation.

3. Here I changed the appearance and gave a name to rod ABCD and placed pin joints at the ends of rods BE and CF

4. Here, I place motors at the bottom of rods BE and CF and specified the proper angular velocities.

5. I then clicked on one of the pin joints and selected to measure force from the measure menu.

6. I added a total of four measurement windows, two for each joint. I then changed the force windows so that one measured as a graph and the other as a numerical number only. These values show the vertical force at each of the pins.

7. I then ran the model for one full rotation. A plot of the forces can be seen for this one rotation.
