Pulling apart an ideal string that is equally strong in all points

I have a finite length string that is equally strong in each point. The strength is finite. I slowly start to pull it apart by both sides. In which point(s) will this string snap? Will it extend indefinitely like a rubber band? Snap in all points at…

How much is important the role of Planck length in the strings theory?

this is Planck length: $$\ell_p=\sqrt {\frac {G.\hbar}{c^3}} .$$ How much is important the role of this length in the strings theory? is this planck's length or newton's length! or maybe both of them!?

Waves on a guitar string

Can there be traveling waves on a string that is attached at both ends (like a guitar string), or does such a configuration allow only standing waves ?

Relieving Tension in a String

I have a zither with movable bridges, and one technique for lowering the pitch of the string on one side of the bridge is to lift the string on the other side. Because the length of the string is remaining the same, the tension must be decreasing,…

Question on Proof of a Wave Speed on a Stretched String

I do not understand why the partial derivative of y with respect to x is $\frac{F_{1}}{F_{t}} = \frac{-dy}{dx}$ Shouldn't the partial derivative of y w.r.t x = 0?

Vibrating string of variable mass

My physical intuition is rather poor so I would appreciate any help. If a string is vibrating and is heavier towards one end and gradually gets lighter towards the other, I find after plotting the eigenfunctions that the standing waves have a…

Why can only gravitons or gravity pass through to other membranes?

String Theory suggests that only gravity and no there type of forces like strong,weak or em can leave a particular membrane and pass through to others.
