EXPERT ANSWER 3A) Hardness is the capacity to resist against scratch. A mineral can be very hard yet still be easy to BREAK, Whereas roughness or strength is resistance to breaking. Taking the example of Diamond to understand it :- Diamond is a hardest mineral known. It will scratch every other mineral. But diamond is …

A structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane strain fracture toughness of 98.9 MPa root m (90 ksi root in.) and a yield strength of 860 MPa (125,000 psi). The flaw size resolution limit of the flaw detection apparatus is 3.0 mm (0.12 in.). If the design stress is one-half of the yield strength and the value of Y is 1.0, determine whether or not a critical flaw for this plate is subject to detection.
