In the bending moment formula M = T x L, what does L represent?

Moment is the turning effect produced by a force, and it’s found by multiplying the force by its lever arm—the perpendicular distance from the pivot to where the force is applied. In the expression M = T × L, T is the tension in the wire, and L is the distance from the pole base (the pivot) to the point where that tension acts. That point is where the wire attaches, which is at the height of the wire above the base. So L represents the height of the wire attachment. The higher the attachment, the larger the moment for the same tension.
