Fuckin google it buddy

What is a crumple zone?

crumple zones

10 ft tall tower made out of note cards that ends under egg starting position.

>>605981
Shit I don't know what what was going on in my head. That's really a great idea.
Thank you.

What note cards, how big, how hard ?
Why do you have to do it ?

>>605986
Around 3 by 5 in.
Doing it for a college physics course.
Just looking for some ideas to get me started

For help on crumple zones have a buddy crash your car into a pole as you record the results. Watch how it crumples yet does not allow the person inside to be crushed, repeat this on a micro scale for an egg.

I take no pleasure in drawing what is probably on the first page of google images for you OP

>>605993
I really appreciate it, anon. That's exactly what I was looking for.

If you can use an unlimited amount of paper and cards, make a chute/slide and see what your teacher says about it.

We get points marked off for size/weight. Though that would work, it's not worth losing points for.

hard boil the egg

just make a box out of paper and fill it with crumpled paper that you crumpled multiple times till it turns soft
done is easy stop being a retard

build this.

My only real concern with this, is that the egg will likely bounce once it hits the floor. I'm sure I could save it from the first impact, but the second could be fatal…say I use the cone/crumpled paper technique, what's to say it doesn't turn over on its side and crack after surviving the initial impact?

This is a homework thread. I remember doing this in high school for TechEd. We had a larger variety of materials but a very limited supply of them. Most people went with parachutes which didn't work.

If you're doing this with paper note cards ask /po/ instead. I'm sure their brains can come up with 1000 kirigami designs for protecting eggs. But don't bother if you're in a hurry, it's a very slow board.

Simple make a tube the shape of your egg and have it slightly taper down throughout the tube. Add stabilizing fins to one end and a cone to the other. Make sure the egg sits nearest to the cone and not the fin. If you like you can add shredded paper inside the cone but the tapper should be good enough to prevent the egg from breaking

>>606057
with that said I still can't help but throwing in my 2 cents. Eggs are virtually indestructible if pressure is only being applied to the top/bottom. They only break from shock trauma to the sides. You could build something with large fins on it so you're egg carrier is shaped like a bomb or a dart. The fins will ensure it lands on it's hardest possible side. Such a design could be done with only 1 or 2 cards as tail fins tapped directly to the egg. It would land with no cushioning, on it's most strong point.

Kind of like
>>605993
but with no padding at all. Just a tail fin cut to the right shape taped on the egg.

Is there a limit on the amount of material you can use?

1. Make a tape parachute to slow it down
2. Since you know which side it'll land on due to the parachute you only need half the amount of material for a crumple zone which will save weight
3. crumple zone

Just tested Idea from 15 feet or my roof and worked like a charm. The should make it a 35ft drop 10ft seems to easy.

paper spring that shit

obvious homework assignment.

you need to learn about corrigation and also, learn your coursework.

I packed $1,000 to $5,000 pieces of art glass, bought on eBay and shipped off to customers for 2 years.

For those, I had multiple crumple zones. It was wrapped in bubble wrap, stuff in a small box with foam peanuts, and that box was put in a larger box with 2 inches of foam peanuts around it on all sides. When we didn't have foam peanuts and bubble wrap, I grabbed up fliers, newspapers, magazines, and junk mail, ripped them up, and crumpled them into loose balls. I never once had a breakage.

In your instance, you use the tape to hold the crumpled note cards to the egg. The stiffness of the note cards will determine the best way to crumple them up and attach them. You may consider making two or more layers with the inner layer shredded and then crumpling the shreds.

>What would a good design be to start with? I'm at a loss…

Sounds like you should get an F in this class then.

Pay more attention in your high school class.

We just did this in my engineering class but ours ended up surviving ~60ft. We had 50 note cards and a roll of scotch tape.

Nice try, the MESA egg drop is for high school and middle school students.

>MESA egg drop
excellent. op just found his solution. make giant ball of popcorn and tape egg in middle.

"The container may not contain any substance that will splatter including peanut butter,
jell-o, liquids, fruits or vegetables (popcorn is okay)"

I did my High School one as a rocket assisted steel frame that was a spike landing aided thing and the egg was packed into an aluminum can with packing beads around it.

Worked from 5 meters. Shit was sketchy though setting off that rocket engine with a push button switch. Loud as fuck too.

Basically turned an engine holder and welded it to a 2"x2" plate where I mounted a 9v a switch and the 4 spikes. Welded a set of nail gussets for the spikes and added nails to the side of each spike at about a 45 to keep it from tipping if it hit sideways.

Did one with a rocket and one without. Both worked somehow.
Not really helpful though I guess. My inner /k/ says to create Wound Vectors for the hydrostatic Shock.

There's a 9th edition out now, apparently. Third result in google. :-) Thanks for the tip.

>>606181
Could do the same with 8 note cards.

Why wont those idiot schools just tell us already how to execute it? I mean we're paying fucking fees and they are making us frustrate. We're there to learn, not to guess shit. Paying students are scratching their heads how the fuck they would do it while the bozo teachers are sitting their ass off laughing deep inside themselves while they get paid. Just give us the fucking knowledge already, FFS

>>605972
parachute on top of egg, to slow it. pointed cone of cards below egg to crumple and absorb impact.

As an Education student, I must say you have no concept of how the whole teaching and learning thing works, hey.

Guess how i know you're going to work a minimum wage job for the rest of your life?

Protip: Rote learning isnt really learning. Remembering things like an autistic meat machine makes you no more useful than a computer.

Look up airless tire designs. Consider the egg the hub. Apply. Bend cards and bind with tape, all the supplies you need for a perfect excecution. Youll have so much spare time youmcan make confetti from the leftover cards, because your design was efficent ane effictive enough to save the egg

One of the most important skills in life is being able to figure stuff out on your own. Not by staring at your feet until you know, but by searching for the pieces of knowledge that you can combine into the answer you need. You are not doing very well, so I'll start you off at level 1 of figuring shit out:

I remember grade 10 physics. Egg thing was pretty meh other than getting to go up on the roof to throw it off. Tooth pick bridges were where it was at.

Anyway, can't they just give you kids a bridge simulator game, or something? You're all just going to good some crap of the web anyway.

>>606061
this is literally a lie
try squeezing an egg and see what happens
