Question: A short 14-in.-square concrete pier is reinforced with four longitudinal #7 bars (7 8 diameter). The ultimate compressive strength of the concrete is 4000 psi and the modulus of elasticity for the steel bars is 30,00,000 psi. The pier supports a load of 100 kips. Compute the portion of the load carried by the concrete and the portion carried by the steel. Compute the stress in each material.
