Hi, I was looking for the actual weight of a shuttlecock, but found two different values for it. On www.shuttlecocks.com, the weight was given as 48-52 metric wt, which I take to mean 48-52 grams. On a page from www.badmintonalley.com, the average weight of a shuttlecock was said to be 5.0 g. Now 5.0 g happens to the weight of a piece of letter-sized paper, so I held them with my right hand, and the shuttlecock felt heavier. But of course I won't be able to tell whether the shuttlecock is 10 times heavier than the piece of paper. Anyone with an electronic balance handy?
feather shuttle weighs 4.7 to 5.2 g, depending on speed rating of the shuttle. I think 4.8 -4.9 g are most commonly used.
Spring Constant of Cork Base Can I tag on another request then? To figure t0 = (m/k)^0.5, which sets the time scale for a shuttlecock to rebound off the stringbed of a badminton racket, I also need the effective spring constant of the cork base of the shuttlecock. My own crude experiment gives me k = 1 x 10^4 N/m, for a 1 mm depression when I squeeze it with about 10 N force. This value disagrees with a crude calculation done starting from the Young modulus of cork by a factor of 100 (i.e. my experiment value for k is too small, compared to crude theory). Anyone able to do a more refined measurement of k?
Take a look at this page, it gives good information about shuttles http://64.233.183.104/search?q=cach...cocks+weight&hl=en&ct=clnk&cd=7&client=safari
my G-shock watch weighs roughly around 130 grams. that means the shuttle is heavier?? then i must be breaking rackets like toothpicks!!
