Re: [Phys-L] bike wheel handles

We modified a bicycle wheel at Pima college by removing the tire and wrapping several spools of Lead/tin solder in place of the rubber, then covered it with electrical tape. Really worked well

Note that axle pegs are characteristic of BMX bikes, which normally
have 20 inch wheels ... but for typical angular momentum demos you'd
rather have something larger.  I recommend 700 mm road-bike tires.


Size less important if one uses a liquid or solid instead of a gas to fill the tyre.

bc thinks pouring Pb into the tyre would be best except for the smell.  [Maybe Hg, Ga or S (melts at ~ 115C)]


p.s. the demo bi-cycle wheel at USSC has a lead "tyre".
