For a physics project, I have to design a rubber band powered car to travel a 4.0 meter course (tile floor) in 5 seconds. One standard rubber band (size #33) was provided by my teacher and only this type of rubber band may be used. The rubber band may be modified in any way. The power of the rubber band must be delivered to the wheels, and no propellers, sling shots, or other launch-type systems are permitted. The chassis/body or wheels of the car may not be purchased. I have honestly no idea where to start with this project, and my teacher is hardly giving the class any direction. My main problem is how to deliver the power of the ruber band to the wheels. Any sort of help or advice would be appreciated. Thanks in advance. | ||

Take your rubber band and connect it to your wheels, whatever they might be, then connect two 2liter pop bottles together by cutting each in half then suspending your rubber band in the middle of the two bottles, with a wheel at either base of the two bottles. Glue the bottles together with hot glue or by some other mannor. So this set up will give you two wheels at either end of two pop bottles glued together with your rubber band stretched inside the bottles connecting your wheels. All you have to do is roll the "car" backwards twisting the rubber band. Then, let go and watch it fly. I hope you understood that. It is difficult to explain without a graphic of some sort. If any body else understands please feel free to simplify. (Message edited by whoo_mythbusters on October 14, 2006) | ||

I need to make a non-motorized car. It can be powered however necessary, but cannot be launched, pushed or pulled. I can use any household supplies that I need, so if anybody has any ideas, it would be a big help. Thanks | ||

Attach the rubber band between the axle and the body of the car. Now when you roll the car backwards, the rubber band winds around the axle. Let the car go, and the rubber unwinds, powering the car. | ||

What physics concepts would these rubber band cars use, and how/why? That's all the information that I need. | ||

I have to create a rubber band car powered by one rubber band(size #64 ). The rubber band can not be cut.It must travel about one meter( 3 feet ) and hold a one pound object(500 grams). PLEASE HELP ME! THIS PROJECT IS WORTH HALF OF MY GRADE! Any advise would be nice. p.s. need advise pretty quickly. Due next Tues. | ||

I just found out my rubber band car can not use a propeller or a sling shot method. And its going to be raced on a carpeted surface.And that the propulsion of the vehicle must be through the wheels.Yeah, HELP! I have tried so many web sites, but they are all normal. They aren't thinking that your car is going to be raced on a carpeted surface. I RELLY NEED HELP!!!!! PLEASE!! | ||

I saw a gizmo book before that uses CD wheels and a toilet paper tube as the axel, it is powered by a rubber band. Obvious details can be seen in the picture below: These are the materials you need, A long and short dowel or BBQ stick, two CD's, a cardboard tube, rubber band, old diskette, tape, and petroleum jelly (not shown)  First, remove the metal center from the diskette, we will be using this as the washer for later. You can discard the remains of the diskette...  Hook the rubber band on the small stick like this,  then insert the rubber band on the CD  then tape it so it won't spin or get loose.  insert the rubber band inside the card board tube,  and into the other CD  For the the last step, insert the rubber band at the "washer" then use the long stick to hold it in place. Don't glue or tape the washer on the CD.  Though you could tape or glue the rest of the parts together the rubber band itself can hold the whole thing together... Don't limit yourself using one rubber band, I only used one so I could assemble it in under one minute... You could use as many rubber bands as you like as long as it can fit the washer's center hole. You could also use petroleum jelly to lubricate the washer... You operate it by spinning the stick (turns may vary on the number of rubber bands)and when you think it's enough set it on the floor and release it... | ||

It does not seem to me that you have read any of the preceding posts on this thread. Scroll up and read what we have told others. You can also use Google: "http://www.google.com/search?q=%22rubber+band+powered+car%22" There is a lot of information on this topic both on this page and elsewhere. | ||

I have a project due next friday and I have to make a rubberband powered car! My teacher wont tell us anything about how to make it. These are the rules: I need to use at least 3 wheels. I can no more than 2 rubberbands. I also have to make the wheels too!! Please I really need help on my project!!! An advise would be very great. But quickly!!!!!!!! | ||

I don't understand. You found the page where many people have described how to build a rubber band powered vehicle, and you then post a question asking how to build a rubber band powered vehicle. What is missing from all the information that can be found directly above your question? | ||

ok guys... from what i've seen above, you know quite abit... but I have a school project of a rubberband car... but there is a catch. I can only use paper, glue, and rubberbands... The car has to be under 500g as well. =/ havent found anything else out on the internet... so lets see if you guys can help too. dead line is like next week, 3-13-09 any kind of glue is ok, but no no pop bottles, no cd's, and no card board. if you can help, thanks again. | ||

| toni (Unregistered Guest) Unregistered guest Posted From: 124.187.76.158 |
hey guys im in grade 10 and i have a physic's assignment, i need to make a self propelled car, i have lots of idea's, and have done a LOT of research. i'm gonna try to make a rubber band car except i can't figure out how i'm meant to join the rubber bands to the axle and the body of the car. Please help, i was reading another page and someone suggusted to use hooks to attach the band to the axle, so that when the car was coasting it wouldn't re-wind its self and slow down the car. but that only made me more confused. any help will be greatly appericated, thanks in advance! =0) | ||
| Patrick (Firewire) Senior Member Username: Firewire Post Number: 134 Registered: 12-2007 |
@ Passerby: The washer is there to reduce the friction of the BBQ stick with the CD wheel. @ Toni: one way to do that is to use a ratchet mechanism to the wheels, so the axle only spins the wheel in one direction and would allow the wheel to spin freely after the rubber band has un-winded. But that would make things complicated. Since you havn't specified that you are limited to a certain design, I would like to suggest that you make a propeller based design. The trick is to lube the wheels and make the car as light-weight as possible so that the propeller won't have a hard time pushing it. If you want a quick instructable from me , just say so. | ||
| Toni (Unregistered Guest) Unregistered guest Posted From: 124.186.239.63 |
thanks that would be great but i do ask that you dumb it down a bit lol because i dont no what a ratchet mechanism is or lubing, if this would help i can choose which objective i can build my car for it's out of maximum velocity, maximum distance, or accuracy to target. um i already have two types of wheels and some wood for the body of my car which is getting cut this weekend so try to reply before then and i was wondering if wind resistance would be a big thing or not, so whether i should cut my car down to a small size the wood is 19 by 7 cm at the moment and the wheels have a radius of 2 and 2.5 thank you so much | ||
| MaryinOhio (Unregistered Guest) Unregistered guest Posted From: 216.255.18.197 |
This is wonderful, thank you! I did exactly as pictured, except I added a bead at the end where the winding stick is. This keeps the stick from rubbing against the CD. I also used two rubber bands for strength. Thanks |
