Final answer:
The material of the guy wire mentioned in the question is A-36 steel, which is often used for its high strength and welding properties in applications like support cables for poles.
Step-by-step explanation:
The guy wire described in the question is made of A-36 steel. A-36 is a common structural steel alloy used in the fabrication of structural shapes, plates, and bars with excellent welding properties, making it ideal for applications like guy wires which require high strength and durability.
In a scenario where a guy wire is used to stabilize a pole at a 90° bend in a power line, the tension within the wire could be critical to counteract the shear forces acting on the pole. Additionally, knowing that the guy wire is made of A-36 steel allows us to utilize its material properties, such as modulus of elasticity and yield strength, to calculate specific stress and strain scenarios, like the tension required to keep a pole straight.
