Force on the string wave

Main Question or Discussion Point

we know that the force at any point of the rope(in the wave position) is tangential.
however at a typical point we have two tangential force oppositely directed.
so they must neutralize each other.
how the force exists in the rope?

The wave causes a rotation between successive points along the string.

So although the horizontal components of the tension cancel, the direction change from the rotation causes a change in the vertical component. It is this change which is the force which moves the elements of the string up and down, whilst maintaining horizontal equilibrium.

Hope this helps

in this case you mean that tention of string in one side of a typical point, is more than another side and
difference between forces has 2 component so that the y component is for oscillation
and the x component is for circular movement aboat the neighboring point!
could you guide me whether it is true or not?
