i want to believe..!!!!

made my night, thank you

you forgot to carry the wumbo

I liked that, but I think the loop would have needed to be larger. The angle it goes up looks more like a ride at the fair. Too sharp for something that is held together by hitches.

Need a bigger loop to lower to the slope, mang.

Also to make sure the tops of the train cars don't get crunched together like soda cans while they're being pushed up against each other.

...you forgot the part where it has to be secured onto the rails.

but there is a problem
the construction would fall apart

Wow. I just got done with my first engineering physics course. I didn't think I'd find a valid application so soon. Well, see you guys. I'm gonna go live the rest of my life without finding a single other application.

Seriously, I probably won't.

i feel like it would need to be faster than 40mph :|

Did you take mass into account in that equation? I'm sure that would make a bit of a difference.

Science up in this bitch!

Why would you think that the centripetal acceleration at the pinnacle is 9.81 m/s2?

It has to be at least that or gravity will have it's way

I know why it has to be at least it, but why does it have to be? Isn't it possible it could be going faster?

It has to be at least 9.81ms^-1 otherwise it'll it wont move in a vertical circle on earth! it's a minimum btw it can be a lot higher and probably is cuz energy is wasted

its from a french commercial.

nice, thats nice

I was looking at your comment for 5 minutes and waited for train to hit him
i'm not a clever man

Here, use this instead next time ;D

How appropriate

IKR?!

Actually, math can find out.

See comment 111, will c/p for ease
Okay, lets get some Math up in this bitch

The formula for Centripetal Acceleration, the speed the train needs to be at the top of the circle, is A=Speed2 / Radius of the circle.

Okay, so since the diameter of the circle is roughly the length of the train, and the train has 4 carriages, then it's Train Carriage x 4. Now, the average train carriage is 75 foot long, so thats 75ft x 4, which is 300ft. Diameter of Circle is 300ft, so radius is 150ft. Have our radius in feet. Since the sum is in Meters, we convert it to 45.72 meters. Theres our radius

We know that A at the pinnacle of the circle is 9.81 m/s2 so thats settled.


To Find the speed necessary to do the loop de loop, we have to mess with the equation a bit.

a= V2 / R
V2 = A x R
V = Square Root (AxR)
Now just add in the numbers

V = SR (9.81 m/s x 45.72)
I'll skipp the calculations and just tell you that the answer is 21.178 meters be second.
Convert that into Kilometers per hour =
63.53 kilometers per hour. So this shit is possible.
Let's call Mythbusters

*slow clap*

I am assuming it is correct. Too lazy to check it.

Yay, four red thumbs haha
Funnyjunk logic at its finest

I know, right? Don't you just love hotdogs?

Sometimes I put hotdogs in my anus

I'm sweating like a homo holding some... hotdogs

yeeeeeeeeeeeee

I first thought a Sentry Gun from TF2 beat him up.

**flexmclargehuge rolled a random image posted in comment #1028340 at FJ Pony Thread 14 **If you look closely you can see that the train is fake.

If you look closely you'll see that you're using an extremely overused joke known by the entire internet.

Sawse, i need it

if only I knew my friend lol

its from a movie i just can not rember the name of it to save my ass from the rape train

look down man :D

i see that you posted it literally seconds before i hit enter but thanks im going to have to watch it again

Great film I remember something weird about testicles at the beginning, can't remember what it is though.....

;D guise....I know the film... this is honesly the first time i've been able to lend some assistance to some fellow funnyjunkers and I feel most happy about it, the film in question is "Gentlemen Broncos" seen it a coule years back and couldn't fucking forget it! enjoy

Couple*

Centrifugal force?

way too bumpy to stay forced down.

Atmosphere inside moves along with the train to have a resistant atmospheric force placed on the cup.
It's moving too slow in the upper loop anyhow to keep the liquid forced inside the cup.
