I think this is a much better answer, especially for the case where I have a wheel which has, say, a diameter of about 100 chain_link_lengths, and 314 links around its circumference. When I set the wheel in motion, the distance round the circumference will be less than 2*pi*r and I have...
I am not sure there needs to be a force in that sense other than the force I apply to the chain/wheels to accelerate the chain.
Recall the person passing me in the x direction, carrying a rectangular sheet of plywood x long by y high, and moving the sheet in the y direction. He sees the...

Thank you! (I wrote my earlier comment before seeing your edit.)
I think I now understand it.
Everything presumably happens during the acceleration, so it would be difficult to explain in detail, but the key fact is that when the chain is up to speed, it can only be 1/3 of its...
Thank you - I hadn't thought of solutions based on the chain breaking which opens up lots of ideas - but I am not sure I agree for two reasons.
I don't see how it answers the charge conservation problem - I will have more charges along the moving top chain alone than I put on the stationary...
I hope someone can point me to some information to assist resolving this apparent SR paradox.
I have two gear wheels with an endless chain passing round them. The axles of the wheels are 100 chain_link_lengths apart, so we have 100 chain links along the top; 100 chain links along the bottom...
