Airplane on a treadmill

Re: Airplane on a treadmill

Dang it, can't get the preview to pull up. I had no idea that they were going to test the myth though for real, I thought it would be a cool one to send into them though. Mythbusters is one of my favorite shows, if I can't catch the new show on its regular day I always catch it on a rerun.

This of course was where your idea came from right?

Neal Boortz radio show, he did mention Mythbusters though I didnt mention it to keep the post intresting

WARNING!! Whatever you do make sure that your wife's pet parakeet is caged and not in the same room as the treadmill and plane....... we would not any accidents!! and the Mythbusters already tested the chicken into the windshield theory!!

Re: Airplane on a treadmill

It's scary that's there enough people out there that somebody could make a TV show about it and actually have people watch it!!

Kind of like if there was a myth that your boat would float higher in the water if you stored your anchor on a piece of styrofoam and they felt they could get enough interest to make a show proving it one way or another ........

I don't see why that would make any difference. But, what was the answer.

We'll half to watch Mythbusters to find out on January 30th. Previews are deceiving.

Obviously your boat will float higher if the anchor is stored on a piece of styrofoam. The gravitational attraction between your anchor and the earth is directly related to the distance of your anchor from the center of the earth. If you raise your anchor higher it weighs less (if you raise it far enough - into space - it won't weigh anything at all). The secret is to use something light enough to raise it (styrofoam) that will not weigh more than the amount of weight you lose by being farther from the center of the earth.

The airplane question has been answered correctly many times in this thread. You just have to decide for yourself who to believe!

Re: Airplane on a treadmill

Here's one more hint for you:

Imagine replacing the airplane's propellor with a big threaded rod that's screwed through a nut attached to the ground. How much effect do you think the speed of the treadmill is going to have on the speed of the airplane when you start the plane's engine?

(Secret Decoder Ring Answer: The airplane's speed will be reduced by the amount of drag caused by the bearings in the spinning airplane wheels. Jack up one wheel on your boat trailer, get it spinning, and that will give you an idea how much power it will take for the plane to have it's tires spin on the conveyer. On second thought, based on many of the questions in the "Trailer" category here, the answer may be: It's impossible to spin!)

Re: Airplane on a treadmill

This is a great question! Here's another variation (same principle though - the propulsive force has nothing to do with the wheels on the conveyor) for you:

If you put only your boat trailer on a conveyor, then start up the conveyor, then start pulling forward with your truck (not on the conveyor), can you move your trailer? If the trailer starts moving forward at 10 MPH, and you crank the conveyor speed in the opposite direction up to 10 MPH, does the trailer speed go to 0 MPH?

The truck is going to move it.

Re: Airplane on a treadmill

The truck is going to move it.

I know it will certainly without question use a fair amount of fuel moving that boat!

Re: Airplane on a treadmill

The truck wheels are not on the conveyor belt so it has nothing to do with the movement of the truck.
The truck is on dry ground and when you put in gear, it's going to move forward.
May drag the trailer wheels along with it, but it will move the boat.

Re: Airplane on a treadmill

I will say angle of attack makes the wing fly. Long ago I can remember going out on very windy days in a little C-152, and using the brakes bouncing the plane into the air in about 10 feet. Those where the days.

We could all gather at my place and put in a pool. Surely there are enough equipment operators/electricians/plumbers here. You being the former pool tech could tell us how to do it. I'll supply the spot and the cold beverage of your choice.

Jan 30th!...Should be a grin! (hope they do better than the Rocket Chevy off a ramp into a mountain today, that blew up)

Um... for some reason I think your logic is wrong but, I can't prove it.

Re: Airplane on a treadmill

Here is one for you. Lets say you jack up all the wheels on your car or boat trailer. Then fill the tires to exactly 30 pounds. When you let the jack down and there is weight on the tires will the pressure in them go up???

No they won't but I never have figured out why myself. Yes, I've done it just to see. Avatars don't lie..........
