Question 3 : Une barre rigide ABCD est utilise pour supporter un poids P = 115 kN. Cette barre rigide est soutenue par deux cbles, le cble BB', ayant une section de 550 mm, et le cble CC', ayant une section de 450 mm. Afin de compenser la charge P, on ajoute un contre-poids W = 275 kN. On dsire savoir le dplacement vertical des points A et D. Utilisez E = 200 GPa. W = 275 kN A B B' 8 m 10 m 4 m 6 m Figure 3: Systme de la question 3 P = 115 kN D
