A corroded metal gusset plate was found on a bridge. It was estimated that the original area of the plate was 750 cm2 and that a
1 answer:
Answer:
estimate the time since construction of the bridge is 6.66 year
Explanation:
given data
area of the plate = 750 cm²
corroded away during use = 2.5 kg
corrosion penetration rate = 0.5 mm/year
density of the alloy = 10 g/cm³
solution
we know here area is express as
CPR = ................1
put here value ans we get t
t =
t = 58400 hour
time = 6.66 year

Answer:
Explanation:
The pressure drop is directly proportional to the length of the pipe. Then, the new pressure drop is two time the previous one.
Explanation:
Step1
In the stress-strain curve of any material, the yield stress is the maximum stress at which material starts yielding.
Step2
Young’s modulus is the constant of proportionality of stress and strain according to hooks law. It is the slope of the slope of the stress-strain curve of the any material under proportional limit.
Step3
Ultimate tensile stress is the maximum stress that induced in the material under application of load.
Step4
Toughness is the strain energy per unit volume up to the fracture point of the stress-strain diagram of any material. This is the area under the curve of stress-strain.
Step5
Point of necking is the point where any material starts necking under application of load in necking region of the stress-strain curve.
Step6
Fracture point is the last point of the stress-strain curve where component fractures under application of load.
All the parameters are shown in below stress-strain curve:
