Problem 6-1 Determine the force in each member of the truss and state if the members are in tension or compression. Units Used: kN = 10 N Given: P 1 = 7 kN P 2 = 7 kN Solution:
3
θ = 45 deg
Initial Guesses: F AB = 1 kN F DC = 1 kN Given Joint A: F AB + F AD cos ( θ ) = 0 ?P 1 ? F AD sin ( θ ) = 0 Joint D: F DB cos ( θ ) ? F AD cos ( θ ) + F DC cos ( θ ) = 0 F AD = 1 kN F CB = 1 kN F DB = 1 kN
(FAD + FDB ? FDC)sin(θ ) ? P2 = 0
Joint C: F CB + FDC sin ( θ ) = 0
