SUMMARY
The problem involves determining the tension in two wires supporting a 100kg sign, with angles of 35˚ and 55˚ to the roof. The weight of the sign is calculated using the formula Fg = mg, resulting in a force of 981 N. To find the tensions T1 and T2 in the wires, one must resolve these tensions into their horizontal and vertical components, ensuring that the sum of the forces in both directions equals zero, as the sign is in equilibrium.
