A 14-in. square concrete post is 6ft tall and reinforced by nine 3/4" diameter steel rods. Assume that the materials are high-strength concrete and ASTM-A36 structural steel.
a.) If a compressive load of 250,000lbs is applied to this column, find the stress in the steel and the stress in the concrete.
b.) Find the total axial deformation (strain) of the column.
