Today at 12pm I finished my last final ever at MIT. I am officially done! I could recap my experience and throw in some philosophical afterthoughts, but for now I’d much rather catch up on some of the sleep I’ve been missing out on the past few years!
Right now, I’m cleaning my room, doing laundry, etc. aka tending to regular life duties that have been neglected in the past few weeks because of the MIT fire hose.
This was months ago, but now that I am free from MIT, I can write about my past semester highlights! Every year, several MIT acapella groups sell serenades for boyfriends to buy their girlfriends, or in my case for friends to simply embarrass other friends. My lil lil, Stephanie, bought me a serenade from the MIT Logarhythms, who sang Miley Cyrus’ “See you again”. Since I knew it was coming ahead of time, I mentally vowed not to be embarrassed when they corned me in the student center, sat me on one of their legs, and sang to me. Despite my preparation it was still awkward. First, I was sitting on a guy’s who was no taller than I was. Second, all the group members intensely stare at you, and I didn’t know where to look. Third, crowds of students and tourists gather round to see what the commotion is. But I took it in and just decided to go with it. The more I got into it, the more they got it into it. Thanks Stephanie! See the below video.
Today was judgment day! For 1.013 Senior Design, one of our major projects is to design a bridge for a third world country in a savannah climate during the flood season. The bridge had to span 10 ft, and the deck had be at least 2 feet above the ground. The failure criteria was that the bridge had to hold 2000lbs of weight, and not deflect more than 1/2 inch.
We decided to use wood since that is a readily available material in the third world, and to do a spin on the classic truss structure. We wanted the design to be visually appealing, so our side trusses formed a V shape. and the planks laid across the top of the bridge.

The underneath V of the bridge. So visually appealing!
It was a beautiful day outside, perfect for bridge testing! There were a whole variety of bridges – arches, a roll-up bridge, and other ones I don’t even know how to describe. It was finally our turn to load our bridge, but as the only all-female group all 5’4’’' or shorter, we were struggling a little bit to raise the 50lb blocks up 3ft in the air. Suddenly all these male onlookers swooped in and loaded our bridge in less than a minute. It didn’t fail, and it passed the deflection test by deflecting only 3/8’’! Most groups don’t pass the deflection requirement since its meant for a highway overpass, so we were proud of our design.

Beautiful Day!
Confident in our design to load another few hundred pounds on it.
Yay! Our hard-work on our bridge paid off!
