Re: overunity" revised" (paul baughn)
lets forget the friction.
will the train move?
yes
how much energy would it take to lift a 100,000 lb car to a height of 1000 ft?
45359kg x 9.8m/sec^2 = 444518.2 N
444518.2 N x 304.8 m = 135489147.36 J
1 car each second = 135489147.36 J/sec
if you lifted a car to this height each second and placed it on the track would the train reach a terminal velocity.
yes it would if air resistance and the rolling friction applied.
if not it would never reach a terminal velocity until the cars were falling off at a rate of 1 per second.
100 fps.
after several hours of doing this would the total amount of kinetic energy of the moving train be more than the total energy required to lift the cars to the 1000 ft height?
of course.
there are 51,800 ft of train on the level track.
518 cars that weigh 100,000 lb each.
without resistance the train would reach a velocity of 100 fps.
ke = 1/2mv^2
518 x 100,000 lb = 51800000 lbs
23495962 kg
1/2 of 23495962 kg = 11747981
100 fps = 30.48 m/sec
30.48 m/sec^2 = 929.0304
ke = 11747981 X 929.0304 = 10,914,231,490 J
at any moment of time you have a input energy of
135,489,147 J/sec
at any moment of time you have a energy output of
10,914,231,490 J/sec
this would apply with water and a pipe also.
what is your point.
rivers do this 24/7
