Subject: Re: [Phys-l] Statics conundrum
Perhaps it will help to specify a particular situation:
Let the beam be hung from three strings of identical properties
(length,
etc), at the two ends of the beam and at L/4. Slow, smooth,
simultaneous
release all along the beam.
Can we determine the tensions in the strings? Why not? How do the
strings
"know what to do"? (I speak as the student that I am.)
