mythbusters does not conduct rigorous scientific experiments but there is a lot of science on the show.

They get some things wrong but they’ve gotten better over the years. The show is a great starting place for discussion.

In the stated myth printed at the top of this thread we are not given any details about the treadmill so we have to make some assumptions.

I think the fact that no details are given means that it is a very generic use of the word tradmill. It means a moving runway. It is not a treadmill you would find in a gym with handrails and sleightly elevated above the ground. (I believe on the show they did use a cartoon of this type of trateadmill but that was just a humorous illustration).

Hi, everybody,

I think this myth depend on the “runway” is long enough or not.

Assume the conveyor belts(runway) is big(or long) as a WW II aircraft carrier’s deck,
The airplane will moving forward, run for a distance and take off.
Just like the Myth Busters did.

If the conveyor belts is small, just as long as airplane, and set it on a aircraft carrier’s front nose(fore),
than the airplane will moving forward, and once it leave the conveyor belts, it will fall into the sea.
Also like the Myth Busters did on the Treadmill.

Anyway, in this myth, without enough runway,
the airplane will not take off.(except the helicopter.)

Admin,

When people add a post it is very difficult to find (Unless they add it to the last post).

I just noticed that someone aded a post and I had to scroll up and check the dates until I found a new post.

It turns out to be a mistaken post. The poster is addressing someone named Heather about some lovely paintings.

Just thought you might want to fix that mistaken post.

Thanks

you are correct about relative wind, however, the airplane will accelerate to the necessary airspeed for take off no matter how the runway moves-the physics of flight don’t care how fast or in what direction the wheels move.

A conveyor belt can’t effect the movement of an airplane because the airplanes wheels are essentially frictionless. They don’t transmit any of the belts force to the airplane body.

A car is completely different. It’s wheels are driven by a motor and they transmit force.

how can a conveyor belt uses friction in a useful way
