After an hour or so I headed back to my room to masticate (chicken spaghetti) and finalize my portion of the project. That was done in due time so that I could head over to Centennial Campus for my Structures project testing (pictures to follow). The test went well overall. Matt and I missed the stiffness by alot, missed the estimated weight by a factor of 2, and our strength to weight was off by a factor of 1/2. The ultimate load was probably the closest of any groups, we held 90lbs. with an estimate of 100lbs. The waiting portion of the testing was not fun, one group ahead of us took more than an hour to 'break' their structure, really it just oozed apart at the glue joints...shotty construction. Ours on the other hand deformed over 1.25" and when it failed you knew it. For me, I heard the pop and then the whiz of a quarter and peice of scrap aluminum fly by my head. For anybody interested in our material of choice Matt and I used Rohacell foam with Marinepoxy as the bonding agent.
After than was over I had to 'help' Matt finish his portion of he Stab. & Control project...don't ask.
I dropped off the project in Broughton and then headed back to my place to get ready for some pick-up Ultimate! I had a good time playing, it had been nearly 2 years since I had played any good pick up and it was nice to be in the swing of things.
With all of my running around today I think I set a record for number of time in and out of my room at 5. Usually I can plan better than that, but today was fairly chaotic day.
Notice how circular holes turn into ovals and the displacement gage is embedded in the structure after failure.
