1.A three-point bending test is performed on a aluminum oxide specimen having a circular cross section of diameter 10.0 mm; the specimen fractured at a load of 3000 N when the distance between the support points was 40 mm. Another test is to be performed on a specimen of this same material, but one that has a square cross section of 15 mm in length. At what load would you expect this specimen to fracture if the support point separation is maintained at 40 mm?

2.In prestressing work, if more than one wire or strand is included in the same duct, why should all wires/strands be stressed at the same time?

3.The contractor ran out of gunite mixture and finished the deep corner of a 5-m-wide swimming pool, with a quarter circle pipe of PVC pipe, . compute the horizontal and vertical forces on the curved panel AB.
