Correct Torque value for Presta Valve?
"Paul Hobson" wrote: (clip) Since the torque is directly proportional, it'd be ton·furlong. (clip) ^^^^^^^^^^^^^ Thanks for noticing the smiley--it was meant to be funny, but it was also meant to be technically correct, so now I will defend it. We have a lever, lifting a load. If we consider every parameter in the lever equation fixed, except the distand from the fulcrum to the applied force, then the force applied to the load will be given by F = k L, where F is the lifting force on the load, in tons, K is a constant of proportionality and L is the distance from the fulcrum to the applied force, in furlongs. For each furlong from fulcrum to applied force, some number of tons will be developed. So the units of k will be "tons/furlong." :-) :-) |

Clarification: amu/megaparsecs would be units for Leos "k" rather tha the Capt'n's Presto torque -- meb |

AMU-Megaparsecs was a clever unit of torque, but AMU is mass, not force and therefore you'd have to multiply by "g"... which is problematical since g is not constant across any reasonable portion of a megaparsec. Dear Diablo, Naturally, the Times-Picayune help desk has only a small selection of units, but luckily we have that one handy, since it's useful for tightening up connections on pesky long-polymer molecules. Sheldon is considering tightening his Presta valve cap to about 0.000000045931759 stone/angstroms. He may need his reading glasses to see the dial--for some reason, it tends to be fuzzy.

Correct Torque value for Presta Valve?
In message , Sheldon Brown
writes I've seen the light and now use a torque wrench for all threaded fasteners and bottlecaps. Unfortunately, I have been unable to find the recommended torque spec for the little knurled nuts on my Presta valves. Anybody got a definitive answer? I've been using 0.0000013 ton/furlongs, but I'm not sure that's quite correct... Can't help with the Presta valves as the finger and thumb adapter is missing from my socket set but this should help with those bottlecaps: http://www.vibrac.com/products/captorque.asp -- Martyn Aldis, e-mail ================================================== ============================ |
