Column is manufactured using concrete (E=4.2×10^3 ksi) and reinforcement is done by A-36 steel rods (E-29x10^3 ksi). Rod has diameter of 0.75 in. and it is subjected to an axial force of 30 kip as shown. Determine the average normal stresses produced in both concrete and steel rods. What is the effect on stress developed in steel rods if thicker cross-section of rods are used? * 4 ft S in. S in.

A mechanical drawing is described as a technical drawing created by engineers following standard layout conventions, terminology, interpretation, and many other factors. It is also known as an engineering drawing.
