Expert Solution

Step 1

To Find :

The capitalized cost for each.

Given :

The new bridge project is being evaluated at $i = 5 %$ .

For concrete:

The construction cost is $$ 50 Million$

The annual $O & M$ is $$ 250, 000$

The life year is $70 year$

For steel:

The construction cost is $$ 50 Million$

The annual $O & M$ is $$ 250, 000$

The life year is $70 year$

Formula used :

The capitalized cost can be obtained as,

$C . C = P + \frac{A}{R}$

Here P is present worth, R is rate,A is annual O&M.

5. An engineer is planning to use gabion retaining wall to protect a section of Kennon road from landslide. A gabion is a wire mesh container filled with rocks. The engineer must estimate the volume of the rock to be used. If the gabion wall will have a thickness of 5ft, estimate the volume of the rocks given the measured depth of the wall every 10 ft of its width based from the road level. width, ft 10 20 30 40 50 60 70 80 90 depth, ft 5 12 20 18 17 13 10 5 a.) estimate the area of the wall using multiple trapezoidal rule with n=9 b.) estimate the area of the wall using single application of Simpson's 3/8 rule c.) estimate the volume of the rocks to be used using the area in a.) and b.)

Required: • explain what is location of centroid by integration is all about. • explain the difference and the meaning of centroid of an area and centroid of a Line. Location of Centroid by Integration Since the centroid is the average position of the points in a figure, integration is the process used to sum up the infinite number of points a figure has. Integration is also equivalent to summing up finite elements. If an area of an element had been expressed as the differential dA, which is a small portion of the whole area A, the equations to determine the centroid of an area would be: Až = S xdA , for centroid with respect to x – axis and Aỹ = SydA, for centroid with respect to y – axis %3D Moreover, if the centroid of a line is to be determined, the equations to be used are: Lx = S xdL , for centroid with respect to x – axis and Lỹ = SydL , for centroid with respect to y – axis Y Y A EDC Centroid of an Area Centroid of a Line
