raft Version 3.0 PageliA 15] Statics 23: Simple Truss Analysis - Method of Joints [with closed caption Engineering Mechanics: Statics* Dr. Yiheng Wang stion 2: For the following truss structure (with memlb and FG all of 60 cm length each), determine the force in member DE. AB, BC, AD, DE, BE, CF 200 N 120 N 160 N 450 (a) oN (c) 257 N(IT) (b) 799N(T) (d) 363 N (C) 1 , 8:12 / 8:20 HP L194OT

Solution

Take joint D. Apply Equilibrium equations.

Take net force in horizontal direction is zero.

F_DE = 0.

So, option A is correct.
