So in Engineering class in school, we were asked to build a marble run, similarly like the one pictured below, that would keep the marble rolling the longest. The run was built using one board with rows/columns of holes, pegs, and rubber bands, and the marble would roll on the rubber bands. So far the longest time was 35 seconds on a board like this:
Does anybody know how you can build the run to keep the marble rolling the longest?
I'd have to put some thought into it but the first thing that I thought of would be to angle the walls so that the marble bounces back up the inclines that it rolls down but leave a small gap in between the wall and the incline so that it's going too fast to fall through the first time and maybe the second. Also play with the tightness of the bands to make them the most bouncy. That seems like a fun little contest though.
you could probably find a way to infinite loop it by just having a steep ass hill leading down to an elastic band, making sort of a trampoline, and bouncing it straight back up to the top of the steep ass hill again..
make it go back and forth, but then have it go up at the end. If it doesn't make sense, it should look like a bunch of sideways J's, this will slow it down more. You might also be able to have it drop at the beginning and then have it bounce most of the way back, and then have it go down a track like the one I described. This would be my idea for the best solution, but you might be able to look it up as it is a fairly common problem.
treadmills are the trick to everything. fat chicks, skiing on grassy flat back yards, OK GO videos.. - jibnut
Run along the width of the board at different with very slight incline, flats, and uphills.
