The discussion revolves around calculating the tension in strings connected to masses, specifically with a setup involving angles and forces. The masses in question are all 1 kg, and a diagram is referenced for clarity.
The discussion is ongoing, with participants providing guidance on setting up the equations and checking assumptions about the forces involved. There is acknowledgment of uncertainty regarding the calculations for additional tensions T3 and T4.
Participants note the importance of correctly identifying the angles and the need to clarify the direction of forces in the equations. There is also mention of a diagram that is essential for understanding the problem setup.

Then use ∑Fx=max and ∑Fy=may. (And you should know what ax and ay are
Yes, good.laladude said:
Almost -- for the y-dir, we use sin instead of cos.
Except for the "=0" part, that is correct.
Yes, except that there should be some sin's in there because of what I said before about the y-direction forces.
Yes, that is the idea.
Have a look at the forces acting on Mass #3.
