8. A center-point loading flexural test was performed on a concrete beam having a size of 100×100×500 mm. The beam is sitting on two supports located at 25 mm from each edge of beam. If the failure load was 17.5 kN, find the flexural strength. 9. Considering the two tests of flexure, 3-points and 4-points, which one is more suitable for bending test and why?

10. The compression strength test was performed on several samples of concrete molded in four types of molds cubes of 0.100 m×0.100 m ×0.100 m and of 0.150 m×0.150 m × 0.150 m, and cylinders having a cross section of d=100 mm by H=200 mm and d=150 mm by H=300 mm, respectively. If the weight of the samples and the loads at failure are as given in the Table. Both cubes and cylinder samples are cast from the same concrete batch under the same conditions and subjected to the same curing method.
