Question

A triangular structure is oriented such that its base rests upon a horizontal surface, its right side is perpendicular to its base, and its left side forms an incline of angle 𝜃 with the base. A pulley is attached to the structure's apex. Three objects (masses m, 2m, and M) are connected by two cords (tensions T1 and T2) and arranged as follows
Masses 2m and m are, respectively, attached to the left and right ends of cord T1 such that mass m is nearest to the structure's apex.
Masses m and M are, respectively, attached to the left and right ends of cord T2 such that cord T2 passes over the pulley and mass M hangs freely.
