sound and tension

[cees10]

i do not knwo how to handle this problem


i am trying to determine a certain tension in a string
let take a example that evryone can understand

suppose i have a bicycle wheel and i want to have all spoke's (strings) the same tesnsion but also determine or that they have the right tension
Let say they must have all 120 kg /f so about 1200 N each

How do i determine this?


any ideas?

i see all kind of problems like damping of hub and rims and that kind of things and how do you get the same frequentie on all strings?

How exactly are you trying to bring LabVIEW into all this? Are you trying to measure the tension from the fundamental frequency?

Here is a formula: http://www.bikexprt.com/bicycle/pitcheqn.htm

to be honest altenbach i still have no idea what whould be the best thing to do this.
do you have a good idea?
