A sample of silicon carbide is broken in three-point bending. The specimen dimensions were 60x6x2 mm and the outer load span was 50 mm. The force to break the specimen was 150 N and the maximum deflection at failure was 232 um. A defect was found on a plane 100 um from the central loading cross-section and 100 um below the tensile surface. Calculate the tensile stress at this point.

| A three point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5,0mm; the specimen fractured at a load of 3000 N when the distance between the support points was 40mm. Another test is to be performed on a specimen of this same material, but one has a square cross section of 15 mm length on each edge. At what load would you expect this specimen to fracture if the support point...

True or False, one point each, Write down F (false) or T (true). (01) In a mechanical design, it is recommended to use standard size/dimension to overcome uncertainties in stress or material strength. (02) Steels' surface fatigue strength can be correlated to their Brinell hardnesses. (03) If a material point has three principal stresses 01 = 02 = 03 = 300kpsi, then the maximum shear stress is Tmax =...
