how it does work a train without electricity?

Question

i need to make a car or a train without electricity or chemical mechanisms or gasoline. Please somebody tell me about it.

Answer 1

Ummm... I hesitate to ask why you want to try to do this, but okay... Since you can't use electricity or gasoline, no conventional motor or engine can be used. You still have to expend energy in some form in order to do work, by definition, so if you're not burning something or converting something to produce that energy, I can only assume you will be using stored potential energy from another source. Two ideas come to mind, neither of them very efficient and neither of them will last for very long: a spring and clockwork mechanism to produce a continuous torque on the wheels, or a receiver full of a pressurized gas that exerts pressure on pistons driving the wheels. Both of these will peter out pretty darn quickly, which is why you won't see any on commercial trains, especially for any trip longer than, oh, say 100 feet. The only other way to do this (since you didn't say where the train would be travelling or whether it would have to make a round trip) is by gravity, the old-fashioned way that mine carts got down the mountain into town and the progenitors of the modern rollercoaster.

Answer 2

You could always try different forms of external propulsion, let's say steam. You may want a parent around, if this a school project. Keep a fire extinguisher handy too. Get a small copper pot with a valve and insert water, with a CONTROLLED fire underneath. Weigh it down, but make sure the wheels move freely. The weight will keep it steady if you make a system using a string to release the valve, don't do it yourself. Make a pipe protruding from the valve pointing out of the back to directionalize the steam, also try experimenting with smaller nozzles, but not too small. You may want to ask your teacher if you could use steam in controlled conditions with a parent before using it, if this is a school project. Other than that, well, never mind carbon dioxide canisters, illegal at school and no way to poke a hole in it without a mechanism. Hmm... Compressed air may work, although it is a mechinism in theory. If you can get an electrical pump, wait no electricity, and a hand pump may count as a mechanism. Anyway, try to get a hand pump to hook onto a valve that can release all the air instantly, and a kind of "cannon" to connect to the back of a train that has free-moving wheels and secured by a row of wheels on the bottom of the track. when you pull the valve, the compressed air shoots out and propels the train. I hope that I was able to help!

Answer 3

Steam It is not a chemical reaction it is a pysical change in the material.

Compressed gas Just pop the valve & go

Rubber band Wind it up

Answer 4

Let horses pull the car or train for you. Know how they always mention about how much horsepower you have under the hood? ;)
