A steel component must support a uniaxial tensile load. The component has three cracks of size: 5 mm, 2.5 mm and 1 mm as shown in the diagram below. The size of the component is substantially larger than the crack size. The tensile stress on the structure is gradually increased from no load. i)Mark (with a ring) on the figure below where you expect the component to fail. i) Calculate at what stress failure will occur.
