Two-Cord Suspension
A weight hanging from a knot held by two cords to the ceiling — the canonical first problem in statics. Two unknown tensions, two equations, no moment: solve it by resolving components or by closing the force triangle.

All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive Ry acts upward, a negative Ry downward; a positive M is counter-clockwise.
