Athree-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 3.5 mm (0.14 in.); the specimen fractured at a load of 950 n (215 lbf) when the distance between the support points was 50 mm (2.0 another test is to be performed on a specimen of this same material, but one that has a square cross section of 12 mm (0.47 in.) length on each edge. at what load would you expect this specimen to fracture if the support point separation is 40 mm (1.6
