What is the transverse load formula?

The transverse load formula is primarily focused on the interaction between cable support structures and the external forces acting on those cables, such as wind pressure. The correct formulation involves calculating the load per unit of span length—this gives a measure of how much load the cable will bear over its length. By incorporating wind pressure, which affects the tension and distribution of forces on the cable, and multiplying it by the diameter of the cable, we account for the increased surface area exposed to these forces.

This option correctly considers all critical factors: the load per foot of span length reflects the weight or strain the cable is to endure, wind pressure quantifies the external environmental stresses, and the diameter of the cable acknowledges how a larger cable surface area might experience greater wind resistance.

In the context of cables, understanding these relationships is vital for ensuring that installations can withstand expected environmental loads while maintaining integrity and functionality.
