Poles subject to heavy transverse loads tend to break at which location?

Heavy transverse loads make a utility pole behave like a cantilever fixed at the ground. The bending moment from a side load is greatest at that fixed base, so the highest stress sits at ground level. That’s where the pole is most likely to crack or fail first under strong transverse forces. The top or mid-span don’t experience the peak bending moment in this setup, and the base-of-the-insulator point is a localized area, not the region with the overall maximum moment. Hence, ground level is the typical failure location.
