What is the sag formula for the timing method?

The sag formula for the timing method emphasizes the relationship between several critical variables influencing the sag in overhead conductors. In this context, the formula is given as D = 48.3(T/2(N))², where D represents the sag, T is the tension in the conductor, and N is the number of spans or sections of the conductor being considered.

This formula comes from a practical application of physics principles, specifically dealing with the balance of forces and the effects of gravity on the conductor. The factor of 48.3 converts the unit of measure into a format that can be easily applied in real-world scenarios. The division of T by 2N reflects the effect of distributing tension across multiple spans, which is critical for accurately calculating how much sag will occur when a conductor is strung over a distance.

In contrast, the other formulas provided do not align with the actual methodology used in the timing method for sag calculations. For example, the incorrect options either misrepresent the relationships between tension, number of spans, and sag, or fail to incorporate the necessary constants and units that are crucial for accurate computations in practical applications involving conductors.
