_____ is the pull of a conductor on a corner structure.

The pull on a corner structure comes from the two spans pulling in different directions, so the corner experiences the vector sum of those tensions. The resulting force acts along the angle bisector of the bend, and this is what the term bisect tension refers to—the tension along the bisector due to the two-span pull. If the tensions in the two spans are T1 and T2 and the angle between them is θ, the magnitude of the pull on the corner is sqrt(T1^2 + T2^2 + 2 T1 T2 cos θ). If the tensions are equal (T1 = T2 = T), this becomes 2T cos(θ/2). This shows why the load on the corner aligns with the angle bisector and how the tension and bend angle determine the total pull.
