IS NOT THE SAME AS SAYING:

The motion of the belt counteracts the forward motion of the plane.
Erm, it's exactly the same. Think it through.

Bramble - please tell us what force is preventing the plane from moving forwards from the thrust generated by the engines.

If the plane doesn't move, something must be holding it back. What?

Skill Leverage started this thread All joking aside, it has been fairly obnoxious, massively down to me I'm sure but, there's only so many times you can explain something before you get exasperated. As I said, thread should be locked imo, there's nothing more to say.

Same rules as before please; no explanation for a little while, no Googling, everyonerich you are banned from participating**.

SL

*To save confusion, the conveyor belt is the same length as the distance required for a 747 to take off from a normal runway; the frictional co-efficient of runway tarmac and the belt are identical, all other variables such as wind and atmospheric conditions can be ignored.
**I'm just kidding (but not really).
Are the planes engines running?

Just your comprehension it would appear Mr. G. LOL.

The only thing that prevents the plane moving forward is the constraint placed upon it by Skills that the motion of the wheels is exactly matched by the motion of the conveyor. While we hold that as a given, the plane isn't going anywhere.

Skill Leverage started this thread Bramble you have to understand that rotational motion of the plane's wheels imparts no lateral force on the plane. That's the point you're not getting, and you don't seem to want to get it so there's really no point in us continuing this debate.

In all seriousness, after conceding defeat in being able to explain myself yesterday I only came back to address Trendie's inputs as he is an intelligent guy, an old friend and I take the extra effort on that score alone.

Having done that, I really am out of ammo and energy on this one.

Can't wait for next week's.....

Skill Leverage started this thread Lol there will be no next week's sadly, as my future colleagues/bosses are probably reading this thinking 'what an obnoxious dick'.
