The first string, with tension T₁, extends from the knot at an angle 0₁ below the horizontal until it connects with the wall on the left. The second string, with tension 7₂. 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. 1 d ed ed ed ed ted leted al Hints Flotalx Pataly Submit T₁ ►& 13% Part (a) Please use the interactive area below to draw the best Free Body Diagram to represent the forces on the knot where the three strings are connected to each other.
