Equilibre D - 39un Solide Soumis A 3 Forces Exercice Corrige Pdf Exclusive

Draw triangle: Start with W vertically down. Then ( R_W ) horizontal right from tip of W? No — better: Sum: ( \vecW + \vecR_W + \vecR_F = 0 ) → ( \vecR_F = - (\vecW + \vecR_W) ). Vector ( \vecW + \vecR_W ) has components: ( (R_W, -800) ). So ( R_F ) has components: ( (-R_W, 800) ).
