thrust is thrust is thrust... as soon as the brakes on the aero-plane are UNlocked and the JET thrust starts to build OR the prop spins up and thrust builds up, the backward speed of the plane will slow and it will come to a stop when the thrust is greater enough to overcome the rolling resistance of the pneumatic tires on the conveyor belt/friction of the bearings from the weight of the plane... Any additional thrust will put him in forward motion...
Fpr what it's worth, a train wheel, any train wheel, sits on top of the railhead on a spot the size of a dime. Eight dimes is all the friction you get. No more, no less. Like I said, there are literally thousands upon thousands of pages of people battling out this question going back to the beginning of the 90's...no one side ever gives in, no one ever gets the other guys point. Personally, I could care less. This thread proves that the same things that made the thread on the first HB so virulent are still here. It was fun, but I'm out. You guys take it from here.....<B>
