For the given truss: Determine all the zero-force members Use the method of section to find the force in members QU and TU. Use the method of joints to find the force In members OK and SH Draw all necessary free-body diagrams. Indicate whether the forces are in tension or in compression. 2d H B d P₂ d a 2d d B d Y A a a V W B X P₂ PARAMETER d = 150+ A+ E P₁800+ C + D P2 = 900+D+E a = 60° B = 45° X1, X2, X3, X4, X5 are unknown P2 U X3 Q X₁ R P a a A B C 0 7 8 d = 150+ 0+ 3 = 153 mm P₁800 + 8 + 9 = 817 N P2 = 900+ 9 + 3 = 912 N X5 K a N D 9 M P₂ E 3
