Magnitude of R = √(80² + 60²) = 100 N Direction: tan(θ) = R_y / R_x (in absolute) = 60/80 = 0.75 → θ ≈ 36.87° above the negative x-axis (i.e., upward left).

Introduction In the world of physics and engineering, understanding the conditions under which an object remains at rest is fundamental. One of the most classic and critical concepts in statics is "l'équilibre d'un solide soumis à trois forces" (the equilibrium of a solid subjected to three forces). Whether you are a high school student in France, a student in francophone Africa, or an engineering aspirant, mastering this principle is non-negotiable. Whether you are a high school student in
