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 job of a groyne at the beach?
A groyne is a structure which is built at least partially underwater to inhibit water flow and control the movement of sediment. The purpose of a groin at the beach is either to create more beach or to prevent the erosion of an existing beach.
Who was the French architect who designed Washington D.C.?
Pierre Charles L'Enfant (born 2 August 1754, Paris, France - died 14 June 1825, Prince George's County, Maryland, USA) created the original design for the city of Washington DC.
What is the starting salary for civil engineers?
it can be calculate as 1xdaily pay of a mason x 30 + 2x daily pay of a mason x experience FOR example a 5 year Experience person minimum Pay should be 600x30=1800 + 2x600x5=6000 grand total=24,000 minimum salary pay (SYED FAISAL BUKHARI +923216000211)
What is the ratio of average shear stress to maximum shear stress for a circular section?
the average shear stress is 3/4 the maximum shear stress for a circular section
What size steel eye beam can safely span 14 feet with a point load of 4000 pounds in the middle?
There are a lot of considerations to be taken into account for sizing steel shapes, especially for a residential home. For instance, what are the load imposed upon the beam? How will the beam be supported? What environment will the beam sit in (i.e. high humidity, moisture, vibration)? A licensed professional engineer or architect in your state can better answer this question.
What are the components of bridges?
chords (top and bottom)
verticals (also called vertical members)
diagonals (also called diagonal members)
floor beams
deck
pinned support (also called a fixed bearing)
roller support (also called an expansion bearing)
abutments (or piers)
Is a suspension bridge better than a cable stayed bridge?
NO
cable stayed bridge is more preferred because if one rope is broken in it then tension is distributed in all other and we get time to repair it that means no sudden failure in it where as in suspension bridge if main cable is cut than it will be destroyed immediately.

What is the shear strength of oak wood?
Is highly variable depending on wood type and moisture content.
How do beam bridges support weight or load on them?
Instead of pushing straight down, the load of an arch bridge is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end.
What happen to the Pressure in the pipe when pipe is change from large to small diameter?
Obviously the pressure goes up, but there are many other factors in play here. You have only told us one tiny piece of the situation.
What is the definition of geotechnical report?
1) Geotechnical report will be used to communicate the site conditions.
A jetty is a structure at the waters edge, starting above high water mark. Extending into the water, often beyond the low water mark, it is designed to give access from the land to ships moored alongside it. A jetty may be a solid structure, like a very thick wall, but is often an open framework.
A groin (groyne in the UK) is situated in a similar place. It is always a solid structure, and is intended to give shelter to ships (or more often small boats) alongside it. It is not intended to give access to the boats. A groin is often called a breakwater. Groins are also used to reduce shoreline erosion along susceptible coastal areas.
Load capacity of w6x15.0 BEAM?
you need to specify the load. axial? bending? how it's supported. this question doesn't have enough detail.
What is lightweight concrete hollow blocks?
the name itself says the concrete used here is of light weight.....the best example of this kind of structure is PANTHELON....
What is the elastic modulus of Limestone?
Intact Limestone can have a Young's modulus (E) ranging from:
9 GPa - 80 GPa.A,B
Poisson's ratio (v) for intact specimens varies from between:
0.2 - 0.3.B
Bulk modulus (K) derived from the above values using the following relation:
K = E / (3(1-(2v))
Bulk Modulus ranges from:
5 GPa - 66.67 GPa
Shear modulus (G) derived from the above values using the following relation:
G = E / 2(1+v)
Shear modulus ranges from:
3.5 GPa to 33.33 GPa
Limestone is a natural earth material and so significant variability in stiffness properties may occur, as such ranges of values are commonly quoted for the strength of rock and other geotechnical materials. Ideally therefore the user would have access to specific lab test data for the rock type in question.

Why you study about shear force and bending moment?
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
The word 'ceramic' comes from the Greek term 'keramike', which means clay.
Ceramics is anything fashioned with clay and usually fired to produce a hard, durable finish, such as plates, other chinaware, tiles, et cetera.
A lean mix simply means that there is more liquid that concrete in the mix. The mix is thin and pours easier. It is sometimes used when you need to make a base on an uneven surface, like dirt. You would pour the lean mix, and then use it to put the more solid mix on top of.
How much did the Bridge Street Bridge cost to build?
Structural steel in today's market is approximately $0.50 per pound not including fabrication costs. After you finalize your design you should add up the weight of each piece and multiply that number by $0.50 to get material costs. You will have to include extra material for scrap because your cut lengths may match lengths available in the market. Fabrication costs will add to the final total price in the range of 50%-100% of the material costs.
What makes more a architect or civil engineer?
The average annual pay for an architect is higher than that of a civil engineer. The average annual income for an architect is $102,000. The average annual income for a civil engineer is $79,000.
Work done with an angle of elevation?
the angle of elevation would be the angle between the horizon and the line of sight to whatever object you are measuring to. Lets say for instance that you see a plane, and you determine that it has an angle of elevation of 30 deg. This means that from the horizon, you would need to look up at an angle of 30 degrees to see that plane. below I linked to a diagram which illustrates it quite well. Hope this helped!
