<p>@RSIuser: my test scores are too low. On the ACT I got 36 on math but only 27 on English :(. And my essays were okay…they were pretty much the same thing as the “about me” on my website, plus some. So, we’ll see, I guess…</p>
<p>Hi guys,
Sorry to interrupt, but do any of you know the answer to my question? thanks :D</p>
<p>@Bimby3: Personally, I would just mail my unupdated transcripts. Mailing out your transcripts the first or second week of February may be too late. Also, I’m pretty sure the test scores need to be official, and I would check with your school again to make sure they can’t put your scores on your transcript (most schools can). However, I would email RSI with both your questions…any advice we have to offer is only speculation. Good luck!</p>
<p>@SniperCat30: What’s the correct answer? I got 22,500*pi. Nevertheless, it’s been a while since I’ve done this type of problem, so I may be a bit rusty.
Also, I suggest you post the problem in a physics thread instead.</p>
<p>Explanation:
I set up my coordinate system such that the hole is at the origin, and the upper base of the cylinder coincides with the line y=10.</p>
<p>Variables: DF = increment of force, DY = increment of y-distance/height, V = volume of disk, W = work, DW = increment of work</p>
<p>Splitting the cylinder into infinitesimally thin disks, we can calculate the increment of force (per disk).
DF=50<em>V=50</em>3^2<em>pi</em>DY=450<em>pi</em>DY</p>
<p>Since DW=DF * y,
DW=450<em>pi</em>DY*y</p>
<p>To find total work, we want to integrate DW with respect to y from y=0 to y=10 (bottom to top of cylinder)
W= integral (450<em>pi</em>y, y, 0, 10) = 22,500*pi</p>
<p>Note: I used calculator notation for the integral, since I couldn’t put the symbol in.</p>
<p>Alternatively, the work is just (weight)(change in height of center of mass), and that’s right out of physics class. So the answer’s just</p>
<p>(weight density)(volume)(change in CM height) = (50 lb/ft^3)(3 ft)^2 (pi)(10 ft)(5 ft)</p>
<p>where the last 5 ft is the CM height. </p>
<p>I guess you’re also using that ridiculous blue donut book? It’s pure hell! Lvdrlvr and I have probably done at least ten of those annoying ball-and-chain or filling-a-tank problems in class already.</p>
<p>thank you ratdeno for the advice! I will check again with my counselor and then email RSI if my school really can’t send certified scores.</p>
<p>@lvdrlvr55, that is indeed the correct answer. Thank you guys very much for the help!</p>
<p>I had a dream last night that I put down all the wrong information on my application…sigh, there’s still 5+ weeks to wait</p>
<p>They cashed the check, but haven’t sent back the postcard for a month! Hope I’m not screwed already…</p>
<p>I received my 5th semester (jr yr 1st sem) report card today. Should I mail that to CEE or is it too late? Our school’s semester ends Jan 15th which was after the RSI app deadline. And I hadn’t taken any AP’s prior to my jr year. Thanks</p>
<p>for official test scores, you can print off the collegeboard website your scores and copy your PSAT scores and send them in yourself. it does additionally help if these scores are on your transcript, but they are not necessary (on the transcript).</p>
<p>btw, i think that the 2 biggest things considered for RSI, beyond the usual qualifications (which most applicants are), are recommendations and essays. </p>
<p>RSI was absolutely awesome and I wish all applicants the best of luck.</p>
<p>Hmm ok we need something to talk about…</p>
<p>Lets talk about previous all-nighters we’ve pulled 
Haha this should get us into the RSI mindset…</p>
<p>My first one was in freshman year for an AP Bio lab report…anyone else remember the fly lab? Mine ended up at around 16 pages…good times xD</p>
<p>Anyone else?</p>

<p>Hi all, just a quick question that’s been slightly bothering me:
You know how they asked you to print out parts 1 and 2 to the application and mail it with all the other materials? Well, how many of you guys printed it out before submitting online? I’m asking this because the formatting for the page is terrible after you submit it…</p>
<p>Three things: (1) I don’t even remember my first all-nighter…perhaps this is a sign that they occur too often??? (2) Don’t worry @bubbletea23, I printed my application after submitting it online as well. It was the only way to include the application number, and you would think that they would expect most applicants to print it out after submission. In fact, on their website they ask you to “submit this online, print and submit with the rest of the mailed application materials”. (3) I really wish that there was some way of finding out whether or not we are accepted before March. I have to finalize my summer plans in the next few weeks and betting on RSI would be quite the gamble :(. Then again, it is the opportunity of a lifetime…</p>
<p>I would like to have other summer plans in case I am rejected, but I con’t find another program that I realy want to go to, and its probably too late anyway. Are there other great programs that I can still apply for?</p>
<p>My back-up plans are non-STEM related, and I’d imagine that it would be too late to apply to most STEM camps.</p>
<p>Lol its like the quite before the storm…</p>
<p>Results in about a month guys! I hope we all get in :D</p>

<p>I am amazed that they can review nearly 2000 application in only three months.</p>
<p>2 months actually…we get them early march :D</p>
<p>It is pretty impressive.</p>

<p>Hi all! I’m back.</p>
<p>There is one more STEM camp that I know of which apparently has an application deadline of March 2nd! It’s not as cool as RSI but it is another option ([SSP</a> - Summer Science Program](<a href=“http://www.summerscience.org/home/index.php]SSP”>Summer Science Program – "The educational experience of a lifetime"…since 1959))</p>
<p>But good luck everyone! I really do not envy the people at CEE who have to choose who to accept.</p>
