## Truss Design Research

Hello Fellow Nerds! If anyone reads these blogs (why one would, I don't know), then they would know that I am doing an independent study on STATICS!!! Ooooh, excitement! Actually, I do find it quite interesting, and since I just finished the first part of the independent study, I am moving on to the research part, which I am SUPER excited for. I will be researching different designs commonly used for trusses/ bridges, learning why engineers use that specific shape in different scenarios. Those w

## Truss Challenge

So as some of you know I am working on a independent study in statics. Well recently I was creating a problem packet for the Principles of Engineering class and one of the problems was NOT FRIENDLY. At first it's all like, oh yeah, this is simple, but as you go deeper into the mathematics of it, it gets messier and eviler (that is now a word). I did eventually get the answer thanks to my knowledge of physics, vectors and sign notation, which really was where the problem was. So now I change all

## The Physics of the Utility Belt

Ok, does anyone know how all of Batman's stuff fits into that belt? So to start off with, Batman's belt has quick-release covers that can be locked and unlocked with a swipe of a thumb for easy access. Just a fun fact. And, there is a collapsable grappling hook in the belt buckle. Which brings up an interesting fact. Batman uses a de-cel monofilament jumpline cord for his hand-held grapnel gun. The reason for his choice in rope is because it can hold up to 400 lbs, making it possible for Batm

## The Physics of the Perfect Engineering Field

After talking so much about my favorite engineering field, I decided to create a QUIZ to find your perfect field of engineering. A nerdy-version of a personality quiz. WIN. By the way, please post your results, I am curious to know how accurate my quiz is. 1. Other than physics, what is your favorite subject? a. Biology b. Chemistry c. Technology d. Math/ Calculus 2. What do you like to do in your free time? a. Logic puzzles b. Tinker

## The Physics of the Batmobile (Frictionless!!!)

As promised, I looked into how fast the Batmobile would go on a frictionless plane instead of the roads of Gotham. To compare the difference, I used everyone's loving friend, Energy. uk= .8 aB= 60 mph in 2.4 seconds (after some conversions....)= 11.17 m/s mB= 4500 lbs (FYI, I was wrong, a tank weighs 135,000 lbs) F-Ff= mBa mBaB- ukmBg= mBa (4500) (11.17) - .8(4500) (9.8)= 4500a a= 10.376 m/s They may not look like a big difference; well, its not in the short distance. x= 1 mile= 160

## The Physics of the Batmobile

1,200 horsepower jet turbine. Darn. I wish I spoke car. Is that a lot? So let's start with the basics on the Batmobile. The Batmobile can go up to 266 mph, which even I know is fast. To put it into perspective, its faster than the typical jet airplane. To top it off, it can accelerate from 0-60 mph in 2.4 seconds. Not bad for a car that probably weighs the equivilancy of a tank. The batmobile can also withstand up to 593.3 C and as low as -145.5 C. Where would it be that hot, the center of a

## The Physics of the Batcave

Welcome back Bat-lovers! So for this blog the theme is the batcave. Home of Batman. Do I really need to say more? What makes the Batcave one of the coolest hideouts in comic book history is because of the equipment and the details. The centerpiece (though it is not actually in the center) is the Batcomputer, a data storehouse and advanced analyzer incorporating multiple hardwired supercomputers. And, time to break the myth, but the Batcomputer is connected to the CIA's networks, allowing Batma

## The Physics of the Batarang

Originally this was going to be about Batman's utlilty belt, but then I had so much fun things to talk about with the batarang I changed my mind. Well, to begin with, the batarangs are NOT a sold piece of hardened steel alloy. It actually folds in half. Another thing to keep in mind, the batarangs are not designed to return to Batman, hence why the design is not very similar to a boomerang. Also, Batman has multiple kinds of batarangs. So when Batman throws one at a rope, he has one for cutti

## The Physics of Textbook Reading

Ok so I think it's fair to say that no one wants to read a textbook, especially a physics one. Me personally, the words just kinda go in one ear and out the other. So here's my tip on how to read the textbook: Don't read the textbook. A lot of you are probably thinking, "YES! I've been doing that all year!" Well, there's more too it. Mr Fullerton is right when he says the textbook can be very helpful, but the way I "read" the textbook is by doing the problems. Obviously you can't just open the

## The Physics of Tetris

Once a month MIT sends me an Admissions newsletter about new things going on at MIT. One of my favorite articles is about how the students turned the outside of a building into a giant tetris videogame. While the students used more engineering than physics, their was still the components of electric circuits needed to create such an awesome hack (which is a prank MIT style). So here's a video of their creation, and all I have to say is that I WANT TO PLAY!!!!:eagerness:

## The Physics of Teaching Penny Physics

Ok, so I totally got this blog idea from denverbroncos, though after thinking about it the two reseaches are not the same like I thought (my bad). Anyways I decided to do this anyways because its uber-physicsy and funny. Basically, Penny wants to learn what Leonard does for a living, and Sheldon's teaching her. This is gonna be interesting...

## The Physics of Sleeping

I must have a thing for thinking about blog posts in the middle of the night. So last night I woke up at 3:00 am because of my sore throat, which makes it extremely painful to swallow, cough, yawn, etc. So, as I lied in bed unable to fall asleep, I thought about the mythbusters episode I watched about making someone wet the bed by sticking their hand in water. But what stuck out to me was that they used the frequency of the brain waves to determine how deeply asleep Adam and Jamie were. As y

## The Physics of Senior Year

So senior year has finally come to an end and we all are saying goodbye. So I thought I would discuss the physics of senior year. The year has had so much physics enwrapped in it, in and outside the classroom. We got to use physics in physics c (duh), calculus, and technology for those who take these classes. With a basic understanding of physics, these classes became easier to learn and master. Outside the classroom, physics was used by every athlete in the school in some shape or form from la

## The Physics of Seasteading

Next year I will be going to college for civil engineering and I can't wait. One of the people in my physics class is always asking me if I'm going to build an Atlantis. Ever since, I have been interested in the idea of building a floating city on water, called seasteading, which is what Atlantis was before it sank supposedly. Current engineers are looking into the idea, using a similar set up as oil rigs, which are held up on platforms that go down to the bottom. The issue is the cost and the p

## The Physics of Schrodinger's Cat: Cartoon Style

Its after midnight and I'm tired. So here are some cartoons about Schrodinger's Cat, which I have been thinking about a lot lately for some reason... [ATTACH=CONFIG]651[/ATTACH][ATTACH=CONFIG]653[/ATTACH] Cartoon #1: "We may, or may not, have cloned Schrodinger's cat" Cartoon @2: "Being simultaneously dead and alive in the box gave me an incredible perspective over the "life, the universe, and everything". And I am here to tell it to the world!"

## The Physics of Roof Trusses II

Ok, I think everyone knows that sequels are rarely as good as the original, but I think The Physics of Roof Trusses II is way better than the first, but that's mostly because I thought that this roof truss was way cooler. So the very last thing I did in my independent study was build a scissor roof truss. The reason why I like this one so much is because of the awesome shape, even if the angles were butts. Anyways, it usually spans up to 20 meters or 65.51 feet and is most commonly found in cat

## The Physics of Picking a President

So as most of you know the election is just a few days away! YAAYYYYYY!!!!! Just kidding. I for the most part don't pay too much attention to politics, but sometimes I find the topics interesting. I, however, do not find this years election very interesting. Too much bad mouthing and he said he said to ruin each other's reputation and poll numbers. Because for the most part I do not care for either candidate, I have decided to use physics to create an equation to help people like me choose a pre

## The Physics of Not Saving because you are tired enough not to for a really long blog

Oh my gosh I am crying on the inside. I was creating a really awesome blog post that everyone would love and I went to backspace a letter and it returned to the home blog page. I lost everything. So I am going to explain why when you are tired you do stupid things such as not save. According to scientists, during sleep your brain sorts through and stores information, replaces chemicals, and solves problem from the day. When you are tired, it's your body's way of saying, "AAAHHHH me tired." Ju

## The Physics of My Dog, Pearl

So my dog just growled and I thought I should do a blog post on her since I cannot think of any ideas. I was just playing fetch with Pearl in my house, which has hard wood floor (the real kind). Pearl ran on the area carpet onto the hardwood, but when she tried to stop, she ended up skidding past the ball into the fireplace (its just a hole in the wall made of brick so she was unharmed). So here's the play-by-play: When Pearl was running on the carpet, she was able to get enough contraction

## The Physics of Music- Faraday Style

Ok, to be completely honest I came up with this idea thanks to Mr. Fullerton and Goalkeeper0. Anyways, whenever someone talks about Faraday's Cage, I think about that scene in Sorcerer's Apprentice. Not only is it a funny movie, but it's got physics in it. Not to mention Nicholas Cage (hahaha Nicholas Cage, Faraday's Cage, no pun intended). What's not to love? So here's a clip from the movie, which is a great and really cool example of Faraday's Cage. Enjoy the Show!

## The Physics of Memorizing Magnetism Equations

Wow. That title is a mouthful. Kinda like the equations in this unit because THERE ARE SOOO MANY. So I am going to help everyone (and myself) and create a list. FM= qv x B --> FM= qvBsinᶿ F= I x B FM= FC --> r= mv/ (qB) Velocity Selector: FM= FE --> v= E/B FB= ʃI (dl x B= μoI/ (2πr) μo= 4π e-7 Maxwell's 2nd Equation: ʃB·dA= 0 σInduced= (1-(1/k)) σFree B-Field due to Current Loop: B= μoI/ (2r) ʃB x dl= μoIpenetrating B= NμoI/ L μ= NIA

## The Physics of Life

As my second to last blog post ever (for a grade, you can't get rid of me that easy!!!), I thought I should simply talk about how physics is in everything we do. so Here are some summer activity examples most people would not think of: Playing on the playground (teeter totter, slides, swings, etc) Computers/ video games Cell Phones Flying a kite Water gun wars Swimming Driving Packaging for college (Force required to pull/carry it, increasing mass) Baking/ throwing cupcakes Sports (Base

## The Physics of Learning About Vectors

I'M BAACCCKKKKK!!!! As stated in my last entry, though it be several months ago, college wont stop me from blog posting. And with my new found wisdom of college life, I thought I should give some advice to the new prisoners, I mean physics C students. The first thing you learn in physics c is vectors, along with the dot and cross product. LEARN, MEMORIZE, MASTER, REPEAT. Not only will they continue to pop up throughout the year in physics, they will continue to pop up in college. I was one of t

## The Physics of Kicking a Cat

As most people know, I can't stand cats, and constantly joke about kicking them. So, I thought it would be appropriate if I did a blog post on it!! I am by far not athletic, so top speed I could probably kick a soccer ball at 15 m/s or 33.354 mi/hr (This is the average low for kids 11-17 ). I also don't kick at much of an angle, but for this we'll say 20 degrees. So here's the math: y- component: height: ? acceleration: 9.8 velocity initial: 15sin20= 5.13 velocity final: 0 time:? v

## The Physics of Halloween

Halloween has just passed, and as a horror film fanatic, I watched the classic Halloween (the original, of course, with Jamie Lee Curtis). At the end of the movie (WARNING: spoiler alert!), Mike Myers falls out the window after being shot multiple times in the chest. Every time I watch that part, I ask how in the world he could have survived? Well, I am going to use to use ol' faithful energy conservation to prove whether or not Mike Myers could have actually survived. Mike Myers fell out of a
