"Looks like we need some math help."
This is one of my favorites because it only matters as a mental exercise.
We have the NMRA weights that ensure good tracking here on our planet, but
what is a perfectly scaled weight? We ventured here before; however nothing
seems to have been resolved. I know we have at least one physics professor
on the list and maybe he can help.
I can't help but feel we should be looking at scaling gravity itself which
of course can't be done on Earth. But what about a planet where the force
of gravity is 1/64th that of our home planet? For example (and if I
remember correctly), our moon is about 1/64th the size (not mass) of Earth,
yet the gravity is 1/6th that of ours. From this we can calculate the
weight, on the moon, of any object we want. Couldn't we apply the same
thought process to our question of what a scale car should weight? So, what
do we need? A planet with 1/64th the mass of earth?
I know it's not important, however, for me it is more fun than counting
rivets.
