We have often spoken of plate stress and how it is transferred to other 
sections/notes as a string(s) broke or were loosened. I have never seen a 
better example than the little Apollo grand I am removing the strings 
from.......
The bass strings are out and I was in the process of removing tension from 
the tenor section.....when 'pong''' a string broke in the octave 5/6 
section!! as I kept removing tension from the tenor, strings kept popping in 
the 5/6 area...a total of six altogether
 As I was relieving tension in the 5/6 area the strings in the top section 
6/7/8 starting breaking also !!
 Now the strings that broke were all kinda really rusty and broke fairly 
easily but I thought it was a perfect example of plate stress and stress 
transferance............
I have never had this happen to me before.
