The signboard truss is designed to support a horizontal wind of 744 lb. a seperate analysis shows that 5/8 of this force is transmitted to the center connection at C and the rest is equally divided between D and B. Calculate the Forces in members BE and BC 5.4 5.4 5.4 A. ▼ Part 1 The free-body diagram of joint D is shown. The members of the truss are assumed to be in tension. Identify the force D, which is...

make sure about your answers. Thank you. Chapter S4, Problem S4/060 The pyramidal truss section BCDEF is symmetric about the vertical x-z plane as shown. Cables AE, AF, and AB support a 6.9-kN load. Determine the force in member BE. The force is positive if in tension, negative if in compression. 360 mm mm C 300 mm 300 mm 330 mm 330 mm 390 mm Y6.9 kN kN Answer: BE = the tolerance +/-2% Click if you would like to...
Problem 1: A lateral load resisting system of a 4-story building consists a K-truss and is shown in the figure below. Based on the ASCE 7-10, the wind load at each floor level was calculated and applied to the truss joints as shown in Figure below. 1. Determine if the truss system is determinate and Stable (support A is pin; and support B is roller) 2. Calculate the support reactions 3. Using any analysis method, calculate the forces in members...
