A short hollow cast iron column of external diameter 30 cm and internal diameter 28 cm is filled with concrete. The column carries a total load of 400 kN. If ECI = 150 GPa and EConc =25 GPa, calculate: (a.)The stress in cast iron and concrete. (b.)What must be the internal diameter of the cast iron column if a load of 450 kN is to be carried and stresses and external diameter of the column remain unchanged?
