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:
Total saving would be of 36.917 $\yr
Explanation:
Given Data:
Degree F
Degree F
A = 30 ft^2
%
Heat loss before previous final value 

= 360 Btu/hr
Heat loss after new value
saving would be 
= 616.1782 kw hr/yr
$
= 36.917 $\yr
Answer:
Human powered generators are the best energy source for the rescue team as it doesn't require any lengthy time consuming resource but only the power of single human being. Just like fossil fuels, the human power is a kind of renewable energy source that does no harm to the environment and can be used whenever required.

Answer:
a)True
Explanation:
Rolling:
Rolling is a metal forming in which a material passes through two or more than two depends on conditions,rolls to produce the desired product.
Ring rolling:
In ring rolling a thick ring compresses by rolls to produce the large diameter ring.Actually volume of material is constant so when diameter of ring increases then to compensate it, the thickness of ring reduces .In simple words we can say that in ring rolling a thick ring of smaller is rolled into a thin ring of larger diameter.
