Answer:
A. Danube
Explanation:
The river shown by number 1 is the Volga.
The river shown by number 2 is Ob.
Rover shown by number 3 is Lena.
<u>These three rivers all flow through Russia. The Danube is not shown in the picture – it does not pass through Russia at all, and it is Russia and its rivers that are depicted in the image.</u>
The Danube flows through the European countries located West of Russia. It starts in Germany, going through Austria, Slovakia, many Balkan countries, Moldova and Ukranie. In the end, it goes in the Black Sea. It is the second-longest European river, after the Volga, and it flows for 2850km.
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
