A concrete cylinder having a diameter of 6 in and a gauge length of 12 in is tested in compression the results of the test are reported in the table as load vs contraction . Draw the stress strain diagram using scales of 1 in = .5ksi and 1 in = .2(10^-3) in./in. From the diagram determine approximately the modulus of elasticity.
