A similar wire annealed while loaded with the stretching 

 weights gave the following values : —

 times, the deflections were : —

Next the wire was caused to vibrate strongly so as to emit 

 a musical note by striking it with a flat board whilst loaded 

 with the weight (1) during the increase as well as during the 

 decrease of the weights, and also whilst loaded with the weights 

 (1) + (2). The values thus obtained are given within brackets, 

 against the values obtained before the vibration : —
