Hi... I just stumbled upon this forum trying to find a reasonable answer to an introductory physics problem I am working on. Maybe someone here could help me. If you have a mass hanging from three wires, how do you compute the tension in each of the wires? It's a conceptual question, I only need to derive the formula for T1, which is actually given to me, but I still can't figure it out... any help would be greatly appreciated.
