@GotsPokemans I teach physics. No student who waited until the night before to start created a car that could travel the required 5m. Their task was to have the fastest average speed (shortest time) for a 5m time trial on the gymnasium floor.
i need to do sometihng like this in physics, but instead we need to make it, do down a ramp(if needed) and stop on a dime (a literal dime) like meters away and i was wondering it you knew if you could make a braking system on this thing?
not that u need this anymore but the way u would do that is figure out how far the car will go with if one inch of string is unraveled. Then, with the given distance of the dime, u would use basic math to figure how many inches of string u will need to get to the dime. Then u can either tie the string around the back axle, or make a hole thru the axle and and pass the string thru the hole and tie it. this will eliminate the "free spin" of the wheels.
lmao thanks like you said i dont need this anymore, i used a wingnut on a threaded rod for the axle and another metal spoke to stabilize the wingnut so it can only go up or down the axle, once it goes far enough it hits a regular hex nut and locks the axle, throw a few smooth bearings in there and there i go. much better than string because when the string overlaps it will stop earlier
Nice Job ! cool school to let you guys use a camera. Also, I trying to get mine done right now , It's due on the same day a GTA IV so the sooner done the better.
yo thomas, sry man but ur wrong. the sampson was closer, but still the real reason it snaps so slow is because of the axle to wheel ratio. a small axle + big (diameter) wheels = slower snap. the long bar helps to
that's crazy dude. i'm building a mouse trap car for my physics class too but i don't know how and i haven't started yet. got any tips? also check out some of my vids i'll upload one of my mousetrap car when i'm finished in like 3 weeks.
because of the bar attached to the mousetrap and the string attached to the axle.and there was something to do with the friction of the wheels on the tile,when i let it go with the wheels in the air it would snap alot faster
buddy its the weight of the steel rods made the axle to snap slower its like fishing. when u dont have a fish hooked it easier and faster to reel in but when u do, its the opposite
very cool school i live in germany there are many dumbasses

i have to build mousetrap car for school and i was wondering
how do you the big whole in the middle of the CD to connect to the small diameter axel
thx :)

really just make sure you sodder the rod to the mouse trap. other than that its pretty simple

Well a job well done, despite ruining your xbox and the fact that Chissus can't teach.

me and a friend made one about a month ago, both 15 years, it ran with 2 wheels like a bike and went just over 15m i think,
its name was biker mouse lol pretty good name if you ask me XD

What did you use for the axle? And how did you get the axle to not move side to side, because mine does that.

i used a steel rod and i put straws over it to keep it from sliding around

that reminds me of 6th grade wen i had to make one of those. i used a rat trap tho and that thing moved

Hey, that's pretty awsome how you made it go that far. How'd you make the mousetrap snap so slow?
