No kidding : the width of a horse is VERY important !!! :-) Did you know that the width of a horse's posterior is the origin of the size of the booster rockets of the Space Shuttle ???

With a bit of work you can probably get it down to 50 variables: Centre of gravity of train Camber of rails Amount of oil/grease/dirt on rails etc..... Elaine :rolleyes: The tigress is here :-D

The mass in this case is unimportant; the radius of the turn and the location of the center of mass are critical. The outer rail in the turn forms a constrained pivot point, while the inner is unconstrained. The line between the outer rail and the center of mass lies at an angle, Ø, with respect to the horizontal, so the gravitational acceleration can be resolved into a tangential component (directed inward) and a radial component (directed along the line toward the rail), both acting as though applied at the center of mass. The centripetal acceleration is horizontal, acting also through the center of mass, and can be resolved into a tangential component (directed outward) and a radial component (directed upward). This centripetal acceleration is given by ac = S2/R. The speed, Sc, at which the tangential acceleration due to gravity equals the tangential acceleration due to turning is critical. Any higher speed will cause the center of mass to be accelerated toward the outside of the turn, eventually causing the train to tip, as the net tangential acceleration will be toward the outside of the turn. Once the center of mass crosses the line of the outside rail, gravitational force alone will be sufficient to drop the train to the siding. Determining the point at which this occurs requires the mass, M, to be known, as the net tangential acceleration (resolved back into a horizontal component) will create a force directed sideways to move the center of mass the width of a horse's ass and beyond the balance point directly over the outer rail. The time required to accomplish this can be calculated, and yields the point on the curve's circumference where the train is inevitably doomed. The solution details are trivial, and are, as usual, left as an exercise for the student. :) It is ok for women not to like sports, so long as they nod in the right places and bring beers at the right times.

There are only 10 kind of people in the world: those who understand binary and those who don't.
