Bending moment is calculated at what location?

Bending moment is defined for a specific cross-section of a member. To determine it, you conceptually cut the pole at the point of interest and consider the loads on one side; the internal moment at that cut reflects those loads about the section. Because you can place this imaginary cut anywhere along the pole, you can calculate the bending moment at any location along its length. In practice, engineers identify the most critical sections (where loads are applied or where the moment is largest), but the fundamental idea is that the bending moment can be determined at any cross-section along the pole.
