Equilibre D 39-un Solide Soumis A 3 Forces Exercice Corrige Pdf May 2026

Forces in x-direction: [ R_x = T \quad (\textsince R \text has a horizontal component toward the right) ]

So ( R = \frac200\sin\alpha = \frac200\sin 67.2° \approx \frac2000.922 \approx 216.9 , N). Forces in x-direction: [ R_x = T \quad

But ( R_x = R \cos(\alpha) ), ( R_y = R \sin(\alpha) ), where ( \alpha ) = angle of ( R ) with horizontal. ( R_y = R \sin(\alpha) )
