(10%) Problem 10: Three ideal massless strings are connected in a single knot as shown in the figure below. The first string, with tension 71, extends from the knot at an angle 0, below the horizontal until it connects with the wall on the left. The second string, with tension T2, extends at an angle 02 with the vertical until it connects with ceiling towards the upper right. The remaining string connects the knot to a suspended weight with mass M. The system is in static equilibrium.
