Yes unless it is a green arrow. Then you have the right away.
Answer:
Yes, fracture will occur
Explanation:
Half length of internal crack will be 4mm/2=2mm=0.002m
To find the dimensionless parameter, we use critical stress crack propagation equation
and making Y the subject
Where Y is the dimensionless parameter, a is half length of crack, K is plane strain fracture toughness, is critical stress required for initiating crack propagation. Substituting the figures given in question we obtain
When the maximum internal crack length is 6mm, half the length of internal crack is 6mm/2=3mm=0.003m
and making K the subject
and substituting 260 MPa for while a is taken as 0.003m and Y is already known
Therefore, fracture toughness at critical stress when maximum internal crack is 6mm is 42.455 Mpa and since it’s greater than 40 Mpa, fracture occurs to the material
Answer:
The size of equalization basin is 6105.6 m³
Explanation:
The average flow is:
flow = ∑flow/n = 9.788/24 = 0.408 m³/s
Where n is the number or observations.
The inflow volume is:
where t is the time interval
in the same way it is calculated the inflow volume for each observation
The outflow volume is:
The volume of flow is:
in the same way it is calculated the volume of flow for each observation. According to the file attach, the highest volume is 6105.6 m³
