Which rail material provides the best traction?

-

of three, nickel provides best traction, brass , aluminum both soft metals deform under (relatively) minimal pressure.

in particular, nickel silver alloy tracks, resistant corrosion, , have amount of strength , wear resistance, comparatively.

amount of weight placed on rails model train not much, coefficient of friction have low effect on trains used in experiment. rolling friction of axle assembly on bearing structure have higher effect on experiment. recommend using graphite lubricant tends stick entire bearing assembly , tend not run out under pressure.

brass, nickel, or aluminum? why? thanks! :)

Is there such thing called a winged spider?

-
of all's answers comical, least. however, have clarify things amateur biologists, here. arachnids classified such having 2 segments bodies, not number of legs.solpugids arachnids, yet have ten legs, , no venom. solpugids include such animals "sun spiders" , "camel spiders" (which massive, , qualify writers call "nightmare fuel"... trust me... few tours in iraq, have seen several of these things). insects have 3 segments bodies. insects have 4 legs... 6-legged flying instects have 8 (yep... wings count "legs") or 10, depending on number of wings. pic in question, photoshopped, sure. no species of arachnid has wings. , if closely, hymenoptera wings.... bee wings, actually. if recall opening monologue "bee movie" (shut up... have kids), you'd recall line says "wings small, , wrong shape", or words effect. if bee can barely manage flight, spider similar wings wouldn't able waft own farts (if spider digestive...
