A Specimen made from a brittle matonal with a cross-section area tonsion until it yielded of 0.004 m² was gradually loaded in at a Lord of 380 KN and fractured Slightly after the yield point. If the Specimon's material observed elashert clashc deformation until fracture, determine the material's toughness in terms of energy absorbed, in kj. Tako £ = 200 GPa.
