How to tell string tension?

[Spadroliken]

Both my Z-force are strung at 27lbs but whenever I hit it with my hands to feel how the tension it's like, both racquets produces a different pitch. Which one is of a higher tension?

[visor]

the one with the higher pitch...

[Spadroliken]

I forgot to mention one weird factor. The one with the higher pitch is the one that was strung at 27lbs but I have not used it for 5 months or so. The one with the lower pitch however, is freshly strung at 27lbs but I don't know why it has a lower pitch. Any idea?

same string, same stringer?

[Spadroliken]

Same string, different stringer. But significant difference.

[visor]

there's your answer... different stringer... if one of them uses ECP machine and the other a manual, then more often than not the ECP is at the correct tension

[Spadroliken]

Um, Same machine too. So...I don't think it's the machine's fault. Could it be the stringer's technique? But they both used the same way of stringing.

Yes. Stringing requires a lot of skill to do well. There is a huge difference in quality between a so-so stringer and an excellent stringer.

Using different strings could also affect the sound, but I don't think it would make much difference.

String frequency depends on length, tension, and also
linear density (hence thickness).

Good find! I had a feeling thinner strings made a higher pitch, but it's so long since I played with them I couldn't be sure.

I'm getting some Zymax 62 tonight, in a rare departure from ole' reliable BG-80, so I shall reaquaint myself with the difference.

Re zm62, don't mishit... or it'll be a really short departure from bg80.

Yes, that's what I thought. And unfortunately I can't blame the stringer this time, 'cos he's absolutely ace.

actually u cant tell, human feelings change everyday..


these u can trust. but they do cost u a fortune.

Fortunately there are a number of free frequency
analyzer apps out there for android and ios.

would be interested to know if there's a different pitch for different strings

Wth? Didn't you read my post above re string frequency factors, and the wiki link.

i guess i need real life "evidence", not just theory :P also how much difference in pitch too
