Problem 7.56
A three-point bending test was performed on an aluminum oxidespecimen having a circular cross section of radius 4.7 mm; thespecimen fractured at a load of 3740 N when the distance betweensupport points was 44 mm. Another test is to be performed on aspecimen of this same material, but one that has a square crosssection of 11 mm in length on each edge. At what load would youexpect this specimen to fracture if the support point separation ismaintained at 44 mm?
