You will locate a two lane highway between the two points (A&B) given on the attached map. A typical cross-section of this road is attached. The standards to be used in this road are as follows:
Design Speed = 50km/h
Min. Radius = 125 m. (Do not use smaller radius)
Max slope = 8%
Side Slope (see figure)
Land Width = 3.5 m
Shoulder Width = 2 m.
For Printing:
1. Print on (A2) papers
2. Use a scale of (1/10000) for horizontal alignment, and (1/200) for vertical alignment.
Requirements

Ve = L* (A1+A2)/2 Case II: One cross section in cut (or fill) the following in fill (or cut). For this case first find the distance where the cut (or fill ends and fill starts using the following approximation). Station (0+100) Elevation 10 20 30 40 50 60 4 x = A1L/ (A1+A2) Then you can calculate the volume of cut and fill as follows: Cut = A1 x/2 and Fill = A2 (L-x)/2 Using these volumes prepare a table as given on the attached table (use metric measures). This table is used in preparation of what is known as, mass diagram. Notice that embankment volumes are adjusted to excavation volumes dividing by swell or shrinkage factors because when earth is excavated its volume change. When preparing this table take embankment (fills) quantities as negative and excavation (cuts) quantities as positive. Finally using the last column (mass curve ordinate) and stations draw the mass-curve. Hints: see the following example.

## Cma Case Analysis Essay

318 Words | 2 PagesWhen I reflect these conservative conditions, CMI’s can charge $1,595 per pad as a maximum price. An additional test by Corey Construction was conducted, and through the same process, we can calculate the maximum price, $2,387 without conservative viewpoint, so it is very close to Kendrick’s result. All detailed calculations for above processes are shown in Exhibit 3 and Exhibit

## Common Denominator Case Study

735 Words | 3 PagesBy multiplying 4 by 2 we get 8, which makes it a common numerator with 8/15, we get 4/7 as 8/14 and can now compare it to 8/15. Since we know that 1 unit cut into 14 equal sizes pieces will produce larger pieces than 1 unit cut into 15 equal size pieces, 4/7 has to be the larger fraction. Common Denominator To find the common denominator of ⅘ and 9/10 we need to multiply ⅘ by 2, making it 8/10. Now that the two fractions have the same denominator we can now compare the two fractions. We can think of each fraction as 1 unit cut into ten equal size pieces.

## Photosynthesis Lab

1040 Words | 5 PagesC is plotted and fitted to a logarithmic-line to illustrate the saturation effect, shown in Figure 1. Then using equation 12.8 in the lab manual, C/Y is calculated and plotted versus C and fitted to a straight line, shown in Figure 2. From the fitted line, Ymax, which is the maximum number of moles of acetic acid that can be adsorbed on the surface of the charcoal per gram of charcoal, can be calculated from the slope. Then, using Ymax and the value of the y-intercept, K, which is the ratio between the rate constant k1 of the forward reaction (adsorption on the charcoal) and the rate constant k-1 (detachment from the charcoal), can be determined. For calculations, refer to Appendix E. Finally, multiplying Ymax by Avagadro’s number will give the number of AA molecules adsorbed on the surface of one gram of charcoal at saturation.

## How Does Le Chatelier Relates How Systems At Equilibrium Respond To Disturbances?

401 Words | 2 PagesIn the given problem, the instructions were given to find the partial pressure of the reactant and the product using different equations. The equations used the formulas of (PNO2)^2/PN2O4=0.60 and PN2O4+PNO2=.050. To find the unknown values, it is necessary to rearrange to solve. After rearranging, continue by putting the values into the quadratic formula to calculate the partial pressure. The quadratic formula was found to be (-0.60±√(〖0.60〗^2-4(1)(-0.30)))/(2(1)), using PNO2 as “x”.

## Ethylene Dibenzoate Synthesis Lab Report

1086 Words | 5 PagesWe can observe a saddle point which is undoubtedly a transition state. The energy at this peak was recorded and compared with the reactant energy to find the activation energy of the compound. \subsection{ Analyzing TZVP and SVP values:} \label{sec:sec02} \begin{figure} \includegraphics[width=\textwidth]{tzvp_svp.png} \centering \label{fig: TZVP vs SVP} \caption{ TZVP vs SVP } \end{figure} The computational protocol we had consisted of three vital steps, the first step was to submit the job for optimizing the chemical compound at ground level. The second was to perform the geometry scan where we can trace the path followed by the $\beta$ -elimination reaction. The objective of the final step was to submit a job to find out the total enthalpy at the transition state so that activation energy can be calculated.

These valued were used to calculate the percentages needed to determine the water and phosphorus content which can be found in the Appendices as well. Table 1 shows the overall data obtained in the experiment. Conclusion Based from the calculations done the percent moisture was found to be 2.45 ± 0.008%. %P(as received)= 5.8 ± 0.008% and %P(dry) = 5.95 ± 0.008%.

## Seismicity Patterns

1012 Words | 5 PagesIn the present study, principal component analysis (PCA) is used for the regionalization of global seismogenic zones using annual seismic energy time series. Principal components analysis is a multivariate statistical technique used to find a few mutually orthogonal linear combinations of the original variables which capture most of the variability present in the data. It is possible to capture the large part of the variance with a small number of components. This methodology has been widely used in meteorology (Kutzbach 1967; Overland and Preisendorfer 1982; Ehrendorfer 1987). Iyengar and Basak (1994) have used PCA technique to group the regions with homogeneous variability of monsoon rainfall.
