Equilibre D 39-un Solide Soumis A 3 Forces Exercice Corrige Pdf [2025]

Given the intersection I, distances: Let’s put coordinates: A = (0,0), B = (5 cos50°, 5 sin50°). Weight at midpoint M = (2.5 cos50°, 2.5 sin50°). Rope at B, horizontal left. Intersection I: Horizontal line through B: y_B = 5 sin50°. Vertical through M: x_M = 2.5 cos50°.

Forces in y-direction: [ R_y = W = 200 , N ] Given the intersection I

So I = (2.5 cos50°, 5 sin50°).
