Which of the following factors won't affect the bisect tension on a sagged line?

• A. Temperature
• B. Line weight
• C. Corner angle
• D. Line tension

Answer: (A)

The correct choice is that temperature does not directly affect the bisect tension on a sagged line. The bisect tension, or the tension that acts at the midpoint of a line, is primarily influenced by the weight of the line itself, the angle of any corners if the line changes direction, and the overall tension being applied to the line.

Line weight contributes to how much sag is present, directly influencing the bisect tension. A heavier line will produce more sag and thus require greater tension to maintain its position. Similarly, the corner angle is significant because it changes the distribution of forces along the line; sharp angles can increase the tension required at points along the line to maintain structure.

Line tension is another critical factor as it determines the force exerted along the length of the line, which directly affects sag and, consequently, the bisect tension.

In contrast, temperature influences materials, potentially affecting their properties (like expansion), but it does not inherently alter the immediate mechanical conditions that govern how the bisect tension operates in a sagged line.
