Final answer:
The true or false status of the minimum tensile strength of the warning line cannot be determined without the specific regulatory reference. Tension in materials like ropes or wires is essential for understanding their performance under force. Tensile strain is a measure of deformation under tensile stress, calculated as the change in length over the original length.
Step-by-step explanation:
The statement regarding the minimum tensile strength of the warning line for a control zone being 2.2 kN (500 lbs) appears to be a safety standard likely related to construction or engineering practices. In contexts like construction safety, certain standards are set to ensure the durability and reliability of equipment such as warning lines. However, without the specific regulatory reference or context, it is impossible to definitively declare the statement as true or false. If this standard corresponds to regulations such as OSHA (Occupational Safety and Health Administration) in the USA, then the truth of the statement would depend on the precise regulatory text. As for the related example about tensile forces, tension is a force that acts along the length of a connector, like the rope in a tug-of-war, when it is subjected to forces pulling on either end. This tension must be below the rope's tensile strength — otherwise, the rope would snap, as in the given scenario. The tensile strain is calculated by dividing the length the wire stretches by the original length of the wire. In the case of a wire stretching 1.0 mm when subjected to a load, with the wire being 2.0 m long, the tensile strain would be 1.0 mm / 2000 mm, which equals 0.0005 or 0.05%.
