Where's center?

Day 2:
Richard and I are getting things done. We have the body, the legs, the displacer, the displacer cap, and the pressure vessel all ready. What we need to do now is pierce both the displacer cap and the pressure vessel with a needle. But here's the catch: we need to pierce both objects directly at their center.

Here's how we solved the problem:
We "blew up" the image on the white board using the overhead projector. We then drew two chords and two perpendicular lines at each of the chords' midpoints and found the center (where the two lines intersected). We then used the "blown up" picture to find the exact middle on the can. It was a tremendous success; we now have a pierced displacer cap.



What lays ahead the next day we work:
We need to pierce the pressure vessel and weld it together with a piece of strong tin and a bolt. That way, the needle will be secure between the tough tin and less likely to unloosen and disconnect the displacer cap to the pressure vessel. We are a long ways to the end, but I feel confident in our endeavors.

Day 1:
Richard and I worked as a team. We divided the work and completed it thoroughly and efficiently. I cut the Slim Fast and Coors Light cans, and Richard created the crank shaft by bending the wires until they matched the given template. I made the legs of the engine by taping the template on to the can and cutting the outline. I used the same method to create the displacer and body.
So far the project is running smoothly; we have yet to encounter any road blocks. We are light years ahead of our counterparts John and Derrick. Good first day, and I hope the entire project will run as smoothly as today.
