A cast-iron bar with a square cross-section of 50 mm is reinforced by placing tw steel plates 50 mm wide and 10 mm thick on opposite sides of the cast-iron bar. The compound rod is 2 m long and is subjected to a suddenly applied load of 100 kN.

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. There is no initial strain before the application of the load. Let Esteel = 200 GPa Determine the internal forces on rods AB, CDE, and FG Determine the displacement of the rigid bar. If the allowable displacement of the horizontal rigid bar is 0.071 mm downwards, what maximum allowable vertical load can be applied for a factor of safety of 3?
