Question 2: For the axially loaded steel plate with an edge crack sketched below, and the provided dimensions and material properties, answer the following questions: a) What is the maximum axial load, \( P \), that can be carried by this plate? b) Is the maximum load in a) governed by ductile or brittle fracture? c) What is the maximum crack size, \( a \), that can be tolerated, if it is required for the intended application that the plate capacity be governed by ductile fracture? d) What is the capacity, \( P \), of the plate corresponding with the crack size calculated in c)? Given: \[ \begin{array}{ll} b=250 \mathrm{~mm} & F_{y}=350 \mathrm{MPa} \\ a=5 \mathrm{~mm} & K_{1 c}=2000 \mathrm{MPa} \cdot \sqrt{\mathrm{mm}} \\ \text { thickness, } t=12 \mathrm{~mm} & Y=1.12 \text { (assume) } \end{array} \]
