Space travel and cycling – two sure ways to get your bone density down to the point where you snap easily…

Hmmm, this has got me thinking.

In the space station, if there was a big enough space to have a smooth track running around the inside of the body of the ISS to accomodate a bike & rider, then how fast could that person go given the lack of gravity? How long would you be able to freewheel until friction would stop you in a gravity free environment? How much G would you feel per mph riding around the loop? Questions, questions, questions. I really should be concentrating on work instead 😆

Piedi, some class mixing up of gravity and vacuum there! Based on your logic, I would answer the following:
a) Ladder
b) Happy Shopper
c) Uma Thurman

😉

So, you’d feel Uma Thurman. Worth a try I reckon

was watching Pulp Fiction in the gym this morning, I think most of my answers today may contain ‘Uma Thurman’ regardless of question. 😳

Back to serious points, If the space station was big enough, to form a pretty big loop, say diameter 100m, and was static in orbit, and you had a smooth loop ‘track’ as you described, i figure in zero G it would be possible to get cycling. Bit like the wall of death motor cycle rides.

Not sure at all of the physics, but I guess if you had some speed, riding around the inside of the curve, you at least wouldn’t need velcro tyres or anything to hold you down.

I would think the speed is similar to earth and determined by puffing power, but Gs in the tight loop circuit might be quite high?

Strewth, I’m going for a lie down. (maybe thinking about Uma Thurman…)

Physics can’t be that tough.

Radius = 50m
Centripetal force = WTF?

awhhhh crap. Was hoping that we might get a glimpse of it leaving the Cape from the Bahamas that week.

F = mv^2/r
so
a = v^2/r
and
v = sqrt(ra)

if a=9.81 (I.E. g) and r = 50m, v would have to be 22m/s which is 49mph

I guess if you were in space with an oxygen tank you could do it 😀
