You build a basic car, with a body and a way to support the front wheels and the back wheels.
Each set of wheels should be firmly attached to an axle, maybe a piece of dowel, so
that when the axle turns, so do the wheels.
Then you need some way to
attach the end of a strong rubber band to the middle of each axle so that
when you rotate the wheels, the rubber band winds around the axle and
stretches tight.
You can do this with a small nail or screw put carefully
through the dowel. The best way to wind the wheels is probably to push down
on the car while you push the car along a surface, like carpet.
once the rubber band is really tight,
you let the car go, and the stored energy in the rubber band unwinds the
axle, and off goes the car
You don't have to have the band wind around
both axles ... you could make it either just frontal drive or
rear-wheel drive, but it probably goes better if you use both axles.
You
could also use two rubber bands, one for the front wheels and one for the
back wheels, with the ends of each rubber band fixed to the middle of the
car.
Remember, the car will go fastest and the most distance if you use a
really BIG strong rubber band, and can wind it up around the axles really
really tight. But if you make it TOO tight or too strong, the car or the axles might break when you wind it up, which is not good and really annoying.
Another way of making a car like this is to make it like the rubber-band
powered toy airplanes. Make a light frame with 4 wheels, and buy a little
toy propeller or take it off a toy airplane, then wind up the rubber band
by winding the propeller. Then when you let go the propeller, it will drive
the car along.
You should attach the rubber band to the car twist the rubber band as far as possible then let it go!
hi
Coil it more or use larger wheels for the vehicle itself
And bye w t f
A rubber band is attached to any fixed surface of the car and then the other end is attached to the rear axle of the car. You wind the car up by turning the back tires but be sure and keep the tires from free spinning until you are ready for the car to go. When you let it go, the rubber band that has been stretched will unwind from the axle and force the cars tires to turn thus pushing the car forward.
Ferdinand Verbiest invented the first car in 1672. It was the first car ever invented and it was powered by steam.
Anything left plugged in and powered up can drain the battery.
very thin sheets of rubber are elastic
A car is not a simple machine because it has hundreds of moving parts, including dozens of forms of simpler machines. Also, a simple machine converts only mechanical energy (kinetic energy) while a full-size car is powered either chemically or electrically.
to make a wind powered car you make a wind powered car
Something light and strong for the car (cardboard box? plastic bottle? Styrofoam?). The biggest and strongest rubber band you can find.
No
destroy it
With great difficulty.
a battery and a toy car..........................
how do you make a rubber band car
car is powered by battery ,petrol,diesel.
There was no ballon powered car.
How do forces from an elastic car account for it's movement
Rubber band car
Two axles and 4 wheels on a board car-like, pump up water rocket attached to the board lengthwise. You have a water powered toy car
