After a late party at the Dude last Tuesday, we finalized all of our engineering designs including car, winch holder, and all the components associated with our machines. We also made a few changes to our original design. First, we add two slices of polyethelene to the inner arm; according to Saint Venant's principle, this can prevent jamming of the telescope. Secondly, we changed the location of the string attachment from the outer arm to the inner arm. After testing our design, we found that there is a major friction existed between the inner and out arms. Pulling the inner arm helps tremendously on overcoming the friction and allows the arm smoothly scoop the PPBs over to the other side. Lastly, we inserted a treaded rod inside of the inner arm; this rod guilds the spring and prevents jamming.
With only a hand full of working days left before the contest, there is still a lot of work needed to be done. We are definitely ready to spend hours and hours in the shop to finish all the machining by the end of this week. This is the most critical stretch of this project. We can see the light of victory, those who stay will be champions!
