Answer:
Im doing this for my coins im so sorry im really stupid. I know quizziz might have the answers though
Explanation:
Answer:
a > 3 mm
so that critical flow is subject to detection
Explanation:
plane strain fracture toughness = 98.9 MPa root m
yield strength = 860 MPa
flaw detection apparatus = 3.0 mm
Y = 1
solution
we know critical stress formula that is
critical stress
.............................1
here K is design stress plane strain fracture toughness and a is length of surface creak
so here length of surface creak will be
length of surface creak a =
put here value
a =
a = 0.0168 m = 16.8 mm = 0.66 in
so
a > 3 mm
so that critical flow is subject to detection
