Civil Engineering
Civil Engineering is a profession of designing and executing structural works that serve the general public, like houses, buildings, roads, etc. A Civil Engineer is an engineer trained in the design and construction of public works, such as bridges or dams, and other large facilities.

What is the difference between the Carey foster bridge and meter bridge?
There is no great difference between between the two in principlebut,
- In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .
- Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
Trussed means a rigid framework, as of wooden beams or metal bars, designed to support a structure, such as a roof.
How noticeable are the scars from a bridge piercing?
Well as long as there has been no issues with the healing of the piercing, and the piercing has been allowed to season (is over a year old) the entry and exit points will be about the same skin tone as the surrounding tissue. So the "scar" wouldn't be too noticeable.
What is consolidation optimum moisture content and maximum dry density?
Consolidation:
Consolidation is the process where pore water pressures dissipate from a fine grained low permeability soil over time which has a load applied to it and is free to drain (the drained condition is soil mechanics).
As the material is of low permeability, as load is applied and the pore water pressures cannot dissipate, they increase in a proportional manner to the load and so resist deformation. As the water slowly escapes from the soil pore spaces however, the pore pressure reduces and the soil skeleton can deform as the pore water in the pore spaces is no longer holding the pores open. Once the pore pressures have completely dissipated (which may take tens of years in very low permeability clays), the pore spaces will have totally closed and the soil has undergone consolidation. This can result in significant deformation and is something that must be taken into account during geotechnical design.
Optimum Moisture Content and Maximum Dry Density
These terms relate to compaction of soils. This is a process where a load is applied to the soil to "squash out" the air in the pore spaces. This acts to decrease the soils volume and so increase it's density (which has the added benefit of increasing the soil's shear strength).
Moisture content is a way of describing the amount of water in a soil and is defined in a number of differing ways.
The degree of saturation is used to describe the ratio of volume of water (VW) in the soil compared to the volume of available pore space (VV).
Sw = VW / VV
As can be seen from the equation ,if the pore spaces are totally filled with water then the volume of water equals the volume of void or pore space and the degree of saturation is 1 (100 % saturated).
As per the consolidation process above, if the moisture content is too high, when you apply a load to a soil, the pore pressures prevent the soil from being compacted as they hold the pore spaces open. As the moisture content decreases the soil becomes more easily deformed (less stiff), however once you decrease the moisture content beyond a certain limit you are increasing the total stress within the soil which in clays acts to increase the shear strength making them more difficult to compact and in courser soils leads to the formation of soil suction (negative pore water pressures) which also acts to increase the soil strength making the process of compaction more difficult.
As such the optimum moisture content is that at which compaction is easiest for a given soil, which then produces the highest (or maximum) density. This is termed the dry density as it is measured based on the change in mass of a soil sample after the water is removed by drying of the sample.
What are some Bridge building team names?
The Span-tastics? Span-kers? Span-Kings?
Span Key and Our Gang? (you might have to Google Spanky and Our Gang)?
Bridge Over Troubled Waters?
If you have a member named Madison, then "The Bridges of Madison [last name]"
(another one that you might have to Google).
Hope you have a sense of humour!
Ruby bridges dream was to get an education. Ruby did not care what the parnets at her school had to say. She walk proud into that school and even though all though parents were yelling at her and threatening her she still prayed for them and that is a hard thing to do for a person that hatyes you. That is the answer to what is ruby bridges dream

What are bearing capacity factors?
Bearing capacity is the ability of the underlying soil to support the foundation loads without shear failure.
Bearing capacity factors are empirically derived factors used in a bearing capacity equation that usually correlates with the angle of internal friction of the soil.
What effect does gravity have on bridges?
The primary effect of gravity on a bridge is that it keeps it "in place" in the wind. The massive weight of the bridge is a key part of its structure and of its structural integrity. Certainly gravity acts to "pull the bridge down" in effect, but we use that to stabilize the structure, turning a "negative" into a "positive" in that light. Gravity transfers forces to the structures that support the bridge, and, in the case of (most) suspension bridges, hold the ends of the main cables to the massive blocks set to maintain the tension of those cables.

What is the difference between a Caisson and Pile?
A caisson is a retaining structure that is normally water tight that is used to allow construction work to be undertaken under dry conditions below the water table (including below the surface of a river or lake). Examples of when a caisson might be used include on a river bed during the construction of bridge pillars and foundations, or during the construction of a shaft.
A pile is a type of deep foundation which usually extends to a significant depth in the ground compared to it's cross sectional area. Piles may be either driven or cast in place.
*It should be noted that the industry in North America uses "caisson" interchangeably with "drilled-shaft"; it is not solely used to describe the water-retaining device. Please see the related link.
How did Pierre L'enfant get to design Washington DC?
He was a civil engineer on loan from the French Army. He was thus, de facto a C.O.E. ( corps of engineers) man. It should be noted while deeply involved in the planning of the capital city, L"enfant- which means child or infant) had nothing to do with the Capitol building which was not begun until l850 and was primarily styled by James Hoban, the architect who also designed the White House. some quiestioner suggested M L"enfanted designed the capitol building which is not so, and note spelling Capitol for the building the o can be remembered from the dome, it has a pronounced dome! a good memory jogger.
How do you convert a standard measurement of 1 to 11.45 to an architectural scale of 8?
"1 to 11.45" is a ratio, which needs no units.
Here's how you get the conversion factor:
(.125"/12") = (1/11.45) * x [dividend & divisor have to agree in units, hence 12" instead of 1']
x = (0.01041666667) / (0.08733624454)
x = 0.11927083337 or 11.927083337% of 1:11.45

(previous answer)
No one has tackled this question in ages because it's too vague, so perhaps I can jar something loose with this.
The standard architectural scale in America is 0.125" = 1 foot. In other words, an eighth of an inch on the drawing is equal to one foot actual size.
But if we don't know what the units are for your so-called "11.45" scale, then we can't answer the question because we can't do the conversion.
