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.)
