Problem 4: Determine the internal force of truss members Given: The bridge truss is loaded as shown. Find: a) Determine the reaction forces at $\mathrm{A}$ and $\mathrm{E}$. b) Identify any zero-force members. c) Do an engineering estimate of whether members $\mathrm{CD},\mathrm{DG}$ and $\mathrm{FG}$ are in compression or tension. d) Use one any method you know to determine the load carried in members CD, DG, and FG. Solution: Method of joint, method of section and finite element analysis FEA (software)
