I can't believe we made it to the end. Tomorrow everyone will finish their spaghetti bridges! Once you are finished with your bridge you may spend the rest of the day working on your final exam.

We'll see you at Johns Hopkins' Homewood campus for bridge breaking on Friday. Check your email for information about parking, our meeting place and times. Be sure to bring your completed final exam on Friday.

Last tips for the final: 1. All lecture notes have been posted on this wiki. 2. Explain everything. 3. If you're stuck on a few problems, write down your ideas, it's better than leaving the problem blank. 4. Additional resources can be found at []

I hope you are enjoying your weekend, and working a bit on Engineering Innovation! If you have any additional questions on the materials lab, please feel free to email us, eielkridge2010@gmail.com. It is due by tomorrow morning, email it to us please! Also the vectors assignment and the statics problem is due. You can find the statics problem in the statics lecture, please assume the load is 100 Newtons, and each member of the truss is 10 meters long. Solve it just like we solved the practice problem, first consider the whole structure, then each joint. These should be handed in on paper, so we can see your work.

Also be prepared to be outside tomorrow for a couple hours. We'll try to beat the heat, but comfortable shoes, a hat could be helpful.

Welcome to Engineering Innovation. Mr. G and I are both thrilled to be spending the month of July with you. We will be teaching you core engineering principles, but even more importantly we will be challenging you to think like an engineer so that you can confidently solve many different types of problems!

Be sure to finish your mousetrap design plans, as another group will be building a mousetrap to your specifications Thursday morning! Plans are due Thursday at 9am, one set per group.
