(10%) Knowing that the maximum bending stress (ơbma.) is equal to the applied bending moment (M) multiplied by the radius of beam (R-d/2) with circular cross section and then (1) MO) . A divided by the moment of inertia of cross section (1), ie., ob,max- bending test is performed on an aluminum oxide specimen having circular cross section of radius 3.8 mm; the specimen fractured at a load of 950 N when the distance between the support points was 60 mm. Another test is to be performed on a specimen of this same material, but one that has a square cross section of 12 mm length on each edge. At what load would you expect this specimen to fracture if the support point separation is 40 mm? Note three-point
