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
This question is incomplete; here is the complete question:
Fourteen-year-old Jean-Claude, an avid video game player, reads a flawed study showing that video game players are smarter than most people. Then he reads a second study with similar flaws proposing that video game players are poor leaders. What would you predict will happen:
A. He would dismiss the findings of the first study and overlook the flaws in the second study.
B. He would now believe that video game players are poor leaders.
C. He would overlook the flaws in the first study and dismiss the findings of the second study.
D. He would now believe that video game players are both smarter and poor leaders.
The correct answer to this question is C. He would overlook the flaws in the first study and dismiss the findings of the second study.
Explanation:
In general, individuals tend to favor information that supports their points of view or preferences, this is a type of cognitive bias known as confirmation bias. Additionally, this is a type of bias because individuals do not consider objectively whether the information is accurate or reliable. This is likely to occur in the case of Jean-Claude because even when the studies are flawed it is likely he supports the first study that shows video game players are smarter. After all, this supports his beliefs and preferences. Moreover, he might dismiss the findings of the second study that is opposite to his preferences.
Explanation:
If different student have different assignment to work with, there would be no chance of copying the assignment. Moreover, students will work on their own thereby inculcating in them work related ethics and self reliance. They can work independently with their own speed and approach.Thus, inculcating in the creativity and originality.
