1. The stress-strain data of a compression test on concrete cylinders are plotted as below. Assume normal-weight concrete is used for the cylinders. The compressive strength is mostly near psi, the modulus of elasticity mostly near 19, and the modulus of rupture of the concrete mostly near (15%). 5 4 Stress (psi x 1000) 3 2 1 0.001 0.002 Strain (in./in.)
