Bending moments arise from which combination of factors?

Bending moments in an OSP path come from forces that try to rotate a component around a point of support. The strongest combination here is the weight of heavy equipment, such as transformers and other hardware, along the run, which creates vertical loads that the supports must resist. When the path includes corners and dead ends, the tensions on each side of a bend aren’t the same, generating a turning effect that creates a moment at those transition points. Together, the load from the equipment and the unbalanced forces at corners and dead ends produce the bending moments engineers must account for in design. Other factors like wind, temperature changes, or soil moisture affect different aspects of the system and don’t primarily drive these bending moments.
