Chapter 11, Problem 11.53SP

A short $\text{14}$ -in.-square concrete pier is reinforced with four longitudinal $\#\text{7}$ bars $\left(\frac{7}{8}\text{in diameter}\right)$ . The ultimate compressive strength of the concrete is $\text{4}000$ psi and the modulus of elasticity for the steel bars is $\text{3}0,00,000$ psi. The pier supports a load of $\text{1}00$ kips. Compute the portion of the load carried by the concrete and the portion carried by the steel. Compute the stress in each material.
