Problem 4a.
You test a concrete cylinder having a diameter of 6.00 in and a gauge length
of 12 in by applying compression forces. The results of your test are reported
in the table as load vs. contraction. Draw, by hand on engineering paper, a
stress-strain diagram using scales of:
1 in. = 0.5 ksi
lin. = 0.2 x 10"

- Problem 20.2 Concrete has a notable capacity against compression stresses but very little capacity against tension stresses (it cracks easily). One strategy to counteract this weakness in tension involves using wires or rods to prestress the concrete beam in regions where flexural tension can be anticipated. Consider the simply-supported beam shown, which has a rectangular cross section of 18" x 12". If concrete has specific weight of 150 pcf (pounds per cubic foot) determine the required tension in rod AB, which runs through the beam so that no tensile stress is developed in the concrete at its center section a-a.
