Maîtriser n’est pas une question de talent, mais de méthode. La clé est de systématiser l’approche : isoler, lister, concourance, triangle ou projection. T=10cos(30∘)≈11

Problem: A uniform rod AB of weight 10 N rests with end A on a rough horizontal floor and end B against a smooth vertical wall. Find the reaction forces at A and B. Solution approach: T=10cos(30∘)≈11

Vertical line at x=1 (midpoint): y = -0.577(1) + 1.154 = 0.577 m above rod. Good. So C = (1, 0.577). T=10cos(30∘)≈11
