PROBLEM SOLVING: A rigid bar is supported by three non-rigid steel rods, as shown. Rods AB and FG are 0.8 m long with a cross-sectional diameter of 30 mm. Rod CDE is made up of equally-long 0.40 – m CD and DE whose cross-sectional diameters are 60 mm and 30 mm, respectively. A 45 kN downward load is applied to the rigid bar.
