Two weights are connected by a weighty, inextensible, homogeneous thread of length l, as shown in the figure. Weights: m1 = m, m2 = 2 / 3m; Thread mass m3 = m / 3. At what length of the vertical segment of the thread x1, the forces acting on the loads on the thread side will be equal? What are these forces equal to? What is the acceleration of the system in this case?

A detailed solution with a brief record of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
