L'équilibre des trois forces concourantes et coplanaire (en utilisant LAME ou triangle des forces)

Follow @physics_unplugged | video description 👇 The “Triangle” is the strongest geometric shape. Its strength comes from its inherent ability to distribute force evenly across its three sides. Unlike other shapes, a triangle cannot be deformed without changing the length of its sides, making it structurally stable. This is why triangles are used in construction, bridges, and trusses, where strength and stability are crucial. In contrast, quadrilaterals and other polygons can easily change shape
