What kind of force acts to stretch or pull an object?

Tension is the force that acts to stretch or pull an object. It occurs in materials when they are subjected to a pulling force, causing elongation. In practical terms, when you pull on a rope, for example, the tension in the rope increases as the force is applied, trying to stretch it. This principle is crucial for linemen, who often work with cables and wires that must be tensioned properly to ensure they perform their function without breaking or sagging excessively.

Understanding tension is essential for ensuring safety and structural integrity in electrical installations, as it influences how lines are installed and maintained under varying loads and environmental conditions.
