Problem 2:

a)  I take a small tack hammer and tap the bridge lightly but firmly 
on its top.  I then give a similar tap with the hammer on the side of 
the bridge.  The difference in the sound produced is very markedly 
different in the two cases.  It needs no trained ear to tell them 
apart.

b)  I take a tuning fork or small tone generator and apply it first 
to the top of the bridge and then to the side of the bridge.  The 
sound emitted from the soundboard is the same in both cases.

Problem 3:

Why can't I use the tack hammer to drive in tuning pins.  Why does it 
just bounce off the punch and fly up to the ceiling?

Answer me those.
