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
Answer: The Aztecs were violent.
Explanation:
Military campaigns accompanied the very rise of the Aztec civilization. Aztec tribal leaders undertook a series of campaigns to strengthen their influence. Many tribes were turned into vassals who paid tribute to them. Aztec religious beliefs led to many violent deaths. They believed that the gods would bring doom if they did not often sacrifice people, and for this purpose, they often used prisoners of war and members of smaller tribal communities.
Throughout history, they have served as a mercenary army to other cities and states, and over time they have become so strong that they have attacked their masters and become absolute rulers. The state's very structure was militaristic and implied constant expansion, which led to a large number of victims. Many conquered peoples had to pay high taxes, and the Aztecs kept proper records of it. All these factors are proof that the Aztecs were a violent civilization.
They have no access to fresh water
