The Snickers Challenge of Theoretical Tonnage

Monday, Joe told me that they use an equation to calculate the theoretical tonnage of a loaded truck used to pave a certain amount of the road. He then challenged me to find the coefficient constant in that equation by taking the measurements of all the other unknowns and solving for it. He also upped the challenge by saying if I got within five numbers of the actual answer, I would win two whole snickers bars. Now, if you thought I wasn’t taking the challenge seriously  before, this was what I needed. TOTALLY GAME TO BRING IT, I was prepared to measure everything at least four times for the most accurate of averages (just kidding haha too lazy).

But then it rained. And poured. And we got soaked through. And the paving had to be cancelled.

UNTIL TODAY.

With the same challenge and the mindset to win all the chocolate, I was dropped off at the paver by Joe with my (ahem his) trusty tiny wheel, map, and field book in hand. Let the calculations begin.

This is the part where I talk about maths (in brackets). Just a heads up.

(The equation is
Theoretical Tonnage = [((Length*width)/9)*(MAGICAL CONSTANT*depth)]/2000
where Length is the length the paver paves with the theoretical tonnage of the truck
width is the width of the road being paved
Magical constant speaks for itself hello
depth is the depth of the road that is being paved
9 and 2000 are used to convert because square yards and pounds.

Now, I assumed 14 feet as the width because it was half the road at a time and my total road width for one street was 28.4 feet. The depth was assumed to be 2 inches (that’s how much they were supposed to grind off). The theoretical tonnage, which is obviously what we actually try to solve for, was supplied to me by the ever to helpful truck tickets with the exact loads and other details on it.

SO now I have
20*2000 = ((Length*14)/9)*(MAGICAL CONSTANT*2) where you just need the length.

To find the length, I used Joe’s wheel and followed along two truck loads completely to get some values around 120.4 and 113.8 ft but then something totally weird happened with the third reading because they were ending the road, and I just got confused what to tape and not, so I scraped that reading and took a fourth one to replace it with, which turned out to be somewhere around 118.blah. I averaged these lengths to actually get 117.5 ft. Now I have a length to work with~)

Plug and chug, and bombdiggity bam bam, you end up with 109.4 as your MAGICAL CONSTANT value. Yes, the caps is very important.

Now, I really doubted myself all of sudden coming out with such a strange constant because most constants are either some degree of 2 (2^2, 2^8, etc.), include a pi or just seem to not make any sense like damn gravitational constant G or electric constant…

Anyhoo, I showed Joe my work and eeeyyyy I was close! The actual constant’s value was 112 (for this kind of surface and leveling binder)! SO I WON MY TWO SNICKERS BARS YUUUUS!!

Joe then taught me how to calculate yield percentages with this information and even though I mixed up the actual and predicted values in my calculation, I understood it and left knowing more about paving.

I came to the office feeling very victorious and found Dobson at his desk. When he found out what I’d been doing this morning, he began to pop quiz me and I think I did pretty well. He then told me about poly binder* and its differences from HMA (hot mix asphalt pavement) and I learned even MORE about pavement xD

*(It’s much finer and identical to sand. Because it’s so much smaller, it’s packed more densely than HMA aggregate is so hence a smaller constant.)

With my sudden abundance of pavement knowledge and utter boredom after managing to finish a suuuper simple warm up code I started yesterday to get force myself to remember syntax, I decided to start a new code. And what better program to code than to code one that uses this equation and at least the mathematically applicable concepts of this knowhow?

However, simple calculations were too easy a code for my taste so I made it a little more interesting using functions and trying to figure out where the heck I’d stored the syntax required for a function to call a function in the depths of Brian.

When I finally figured the code out, I was apparently too expressive with my triumph and Dobson asked what reason I had to be punching the air… Can’t a girl just be pumped at her desk? xD

Sooo I kind of told him about my being a CS minor and coding for fun and since I’d just told him all that, I decided to gush about this new code I’d just figured out. I was pretty proud cuz it wasn’t just some useless gibberish to entertain others and myself, but actually useful should we need it.

And it’s not like my coding is a secret, but I did want to keep it under wraps because of how I fail at all other things computer related and I can’t give tech support to save my life. My tech curse is a true struggle, okay. So I didn’t want to give the impression that I’m actually a computer person because HAH, isn’t that a laugh?

But yeah, that was that for today :3 Let’s see what happens tomorrow~ Will I win more chocolate? ONLY TIME WILL TELL ❤

Exam Prep/Freak Out/Past Paper Rage

Yeah, yeah, i know, i should be studying right now. and chill out, i AM. im doing physics MCQ past papers on Xtremepapers.com right now. so yeah.

but i am freaked. i mean, ive got the most important exams of my life in 6 days- wait, no its past midnight so technically five days. not like im counting. oh no. my friends do that for me. ‘only ___ days til our exams, like, ohmagooodddd!!’ you are not making the pressure any easier to deal with, oh dearest friends of mine -.-

so anyways, i was supposed to get my past paper booklets yesterday. i ordered them on sat, paid for 75% of them, and even had a witness. buuut, evil photocopier dude, LOST my order, and on top of that, FORGOT to print them out. so i was told to pick them up today. but, boy, did i freak out. i cried and cried, that theres only a week left, and the freakin loser just cost me a day of my prep time! grrr…but i finally got them today, so im feeling a loooot better about my prep, although im still freaking and ill tell you why.

one, im not a genius nor a nerd; im not adil nor a fiza. ive only started preparing for Bio. (theory is right after the atps.) and ive done math past papers sorta at my math tution. but otherwise, i havent studied shit seriously for physics, and i havent as yet TOUCHED chemistry. so im freaking out majorly about chemistry…

And Math. see, i havent practiced math in atleast a yr, since i got sir sohrab as my teacher, and im totally out of practice and my prep is literally less than one fourth the prep i had LAST year when i attended sir farid’s math tution and didnt even GIVE the exam last year…so very veryyy scared about even math. and i used to be better than adil at it too!! >.< aaarrrggghhhh

speaking of genius adil, i talked to his mom the day we were getting our mock results (were childhood friends;ive known him since 3rd grade) and shes going on how shes forcing a genius like adil to study 8 hours a day. lady, im not even studying 3! 3 hours, max, breaks included. im soooo scaaared =(

and and literature. i havent even ever once finished reading the entire wuthering heights. when i went off to the national debating thing, i missed loads of stuff, and havent really read up on what i missed. soo yeaaah. there shall always be apprehensive when it comes to the literarure exam, regardless of your mock grade (i got a 82%! the only one in class who got over 80! ME! and A!! =O) and prep, and grasp of the storyline/plot/ coursework, basically.

and then theres loaaads of nervousness when it comes down to the science subjects too..very much so…i hope i truly pray for atleast an A in physics so i dont have to regive it…

i hope and pray these cursed exams go well. then i can finally look forward to a whole summer vacation of nothingness and  , eventually, boredome. ah, but that boredome is still much more preffered over this evil evil exam time, no? =P

i cant wait for this stuff to end….

and i do promise, as soon as my exams end, ill update my blog. bring it up to speed. ill put all my wacko weirdo dreams up. ill add a bunch more of gahssip junk from the Lyla and co. group. and ill talk more about random shiz again =)

until then, toodles~

haha, toodles =P pathetic…

Later, Homies!

yeaaah, i know the ‘homies’ doesnt make it all that much cooler…=P
