Answer:
Check the explanation
Explanation:
Single Unit Truck ESAL = 43.38 + 5.16 = 48.54
Semi Unit Truck ESAL = 43.38+ 6.00+7.4 = 56.78
So total ESAL's during design life = (400*48.54 + 350*56.78)*365*10/18000 = (19416+19873)*3650= 3939
Kindly check the attached image
Here
Reliability = 95% = 0.95, therefore ZR = -1.645, S0 = 0.4, MR = 18
Delta PSI = 4.2-2.5= 1.7
Resilient Modulus = 18000 psi, So MR = 18
Assume SN = 3.0 for flexible pavements
There W18 calculates to 0.26807
So
log10 (3939) = 9.36*log10(SN+1) -.2/(.4+1094/(SN+1)5.19)) -6.01
Structural Number SN = a1*d1 + a2*d2 *m2 +a2*d3 *m3
= a1*d1 + a2*d2 +a2*d3
Answer:
Explanation:
Data given
temperature =700c
Density=10.35g/cm^3
but
Nv is the number of vacant site and N is the number of lattice site.
Since the number of lattice site can also b computed as
if we substitute the value of the number of lattice into the first equation, we arrive at
Answer:
Explanation:
, integrated circuit packaging is the final stage of semiconductor device fabrication, in which the block of semiconductor material is encapsulated in a supporting case that prevents physical damage and corrosion.
Let's not take into account atmospheric pressure.
Pressure P = Pressure of oil column + Pressure of water column
= h1 . d1.g + h2.d2. g
=( 0.5 x 800 x 9.8) + ( 1x 1000x 9.8) = 3920+ 9800 = 13720
Hence guage pressure at bottom is
P= 13720 N/ m^2
Answer:
Stress corrosion cracking
Explanation:
This occurs when susceptible materials subjected to an environment that causes cracking effect by the production of folds and tensile stress. This also depends upon the nature of the corrosive environment.
Factors like high-temperature water, along with Carbonization and chlorination, static stress, and material properties.
