The discussion focuses on calculating the tension in two wires supporting a street light weighing 150N, with one wire at a 30-degree angle and the other at a 45-degree angle. To solve this, participants emphasize the importance of breaking down the forces into vertical and horizontal components using trigonometric functions, specifically sine and cosine. The equilibrium condition states that the sum of the vertical forces must equal the weight of the light, while the horizontal components must cancel each other out. This method provides a clear approach to determining the tension in each wire.
