Answer:
Fabrication benefits
Explanation:
Onsite construction can certainly begin more quickly when you are using concrete, stone, or brick. However, total construction time will lag behind that of building with steel. These materials require time to prepare and cure; and they result in more waste to move off site and dispose of.
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
