Answer:
Explanation:
The formula for critical stress is
K is the plane strain fracture toughness
Y is dimensionless parameters
We are to Determine the Critical stress
Now replacing the critical stress with 54.8
a with 0.2mm = 0.2 x 10⁻³
Y with 1
The fracture will not occur because this material can handle a stress of 2186.20Mpa before fracture. it is obvious that is greater than 2023Mpa
Therefore, the specimen does not failure for surface crack of 0.2mm
Driving alone without the distraction from passengers reduces the risks you face in driving.
True
There is 3 inches in one square
Input: what is put in, taken in, or operated on by any process or system.

Answer:
The ACH is 12/h
Solution:
As per the question:
Area of the space, 
Height of the given space, h = 10 ft
Air flow rate, 
Now, to find the Air Change Rate (ACH):
We calculate the Volume of the given space:
Now, the ACH per min:
= 
Now, ACH per hour:
=
