How do you build a valedrome?

Since this is a school project, your teacher probably wants to you to learn more than just how to build one.  \n\nLearn to use the library.  Learn to use internet search engines.  Learn to spell what you want to build.  Learn to be self reliant.

for this u need special grade pure silicon.pieces of almost 2 square cm need to be linked by means of silver in order to prevent loss of energy.this arrangement should be erected in a place which receives maximum sunlight.

Here's a link to a PDF file I wrote consisting of all the steps involved (though not quick enough to beat the other two answerers...)\n\nhttp://prash4.esmartdesign.com/ans2.pdf

Get some metal and weld it all together, some wheels, some tires, a couple pieces of rubber for handle bars and pedals, a few feet of chain, and a wicker basket for the front and you're set. =) Oh and a cushion for a seat...don't want to forget the seat. Ouch... =)

I am not sure that you can make a simple pomp. What would make it stand out if it were simple? Maybe just make it big?

Personally I would use 2 metal rods and a ball bearing or marble.  bend rods so they are spaced the same with loops first and then hills.  then find a way to project marble or ? with enough force to stay on track without falling off. try different speeds and re bending rods until satisfactory results are obtained.\n\nThat would be much easier than trying to do all the math required, then obtaining the speeds and angles required to build an actual roller coaster.\nThis should be acceptable for classroom project.

There are usually local shops that build race cars. ask someone that races at a local track who built there car, chances are that a local shop did.

If you want to build it up original, check out http://www.vintagebmx.com\n\nMany people on that board swap and rebuild BMX bikes.

It all began with a simple puzzle box created by Toymaker Phillipe Lemarchand in the 18th century. Called the "Lament Configuration," the toymaker intended that the puzzle box serve as a gift that would bring enchantment to all who possessed it.\nTruly, this box would be visually appealing as it would be entertaining. Lemarchand painstakingly carved the wood puzzle pieces, covered it with black lacquer and decorated it with thin gold ornamental designs. From every interlocking twist and crevice in the Lament Configuration, however, lay more than a simple puzzle. \n\nThe Lament Configuration, with all its amazing powers, was the door to hell. \n\n The Lament Configuration and Pinhead, the Black Prince of Hell, has already unleashed its horror upon an unwitting world. Now in the 22nd Century, scientist Paul Marchand strives to banish the evil which his ancestor (Phillipe Lemarchand) had allowed enter the world through the Lament Configuration. Unlocking the secret to the simple puzzle box, Marchand must use his knowledge to trap Pinhead in order to save the world.

get like a lever, those moving stuff that you can place stuff on then just roll it. Or get more than 1 person

Go to the website. Ask for the instructions. Download the instructions or have them mailed to you. Once you get the instructions start assemblage!

I have never seen anything like blueprints. We have made tracks, and they always evolve as you build them, and as you use them. I'm guessing you are going to use dirt, so just keep fooling around in your space and see how you want the turns, and how tight they should be. Learn how long of a stretch your go cart needs to get to top speed, and make your straight aways about that long. Also, if you are going to do jumps, add them after you have built the track, and put them in places that are easy for people to pass on, that always makes it more interesting.\n\nI would seriously just keep foolling around until it makes sense.\n\nHave fun.

Consider the five basic machines, The lever and fulcrum, The inclined plain, The wheel and axle, The screw and the pulley.\n\nStart with a boyscout pine block racer kit, sand the wheels so that the tread is rounded rather than flat to reduce friction. for the undriven wheels put the nails in the wheels and deposit a liberal amount of petroleum based oil on the axle. This will cause the plastic to swell slightly for a good fit to the axles to prevent wobble, be sure to clean all the flash off of the nails first and polish them.\n\nThe driven wheels willneed a fixed axle that connects the wheels.

Sticking by the rules you specified;\n\nConstruct an inclined channel (ramp) where the 1 kg (2 lbs)weight (hopefully a metal ball) falls and accelerated by gravity. place the car that will catch and hold the ball at the end of the ramp. The falling ball's inertia will propel the car almost equal to its speed and may reach more than 1 meter on a flat even surface, design the car with low center of gravity, with less than half the weight of the propellant ball (weight) as a consideration.\n\n************* \n\nAh, New data acquired --- resolution: same application of inertial force using a rigid pendulum.\n\nConstruct a pendulum with the required height putting the fulcrum point at 10 cm directly above the floor of the car, giving you a swing radius of 10 cm from top to bottom, use a cardboard/plastic tube (shute) to carry the pill bottle but loose enough to set it free after a sudden stop once it reaches the bottom where the position of the pill bottle is parallel with the floor of the car. This configuration may not give you as much distance relying on gravity alone but may be able to get 1 meter if conditions are favorable, pertaining to weight of car and means of motion (wheel and shaft should be well oiled for free-wheeling), relevant to weight of falling object, unless you are allowed to spring load the fulcrum. You can put the fulcrum as part of the car (but it will add more weight/ but you wont need the shute, all components will be integrated), or as a separate launcher (which you will need the shute). make sure the center of gravity on the car is low for stability. when integration of all component is involved make the wheel base equally wide as 10 cm. If just for the pill bottle, just narrow enough to carry the bottle.\n\nmy idea: http://server4.pictiger.com/img/124010/other/1-kg-inertia-car.jpg\n\nInnovation is part application and part logical creativity. Isn't science great!\n~meow

build them yourself with a program like the GIMP or Jasc. it aint that hard... or you can get some off of google image search probably.
