Some people call it an air pocket in the concrete or a void. What is the purpose of the gap in the road on this bridge?
Purpose of the gap in the road is to allow the road to exPAnd and contract with temperature changes without causing damage or deformation to the road.
What is the tensile strength of wood?
The tensile strength of a material is the value at which the material fails when subjected to a tensile force.
Tensile means a force pulling the wood fibers lengthwise, as opposed to a compressive force. There are a lot of different types and load cases for wood, so there is not one answer to this question. For example, wood used outside will fail at a lower load than wood inside. Wood is also anisotropic, i. A good reference for material strength data for most species and grades of commercially available wood can be found in the American Institute of Timber Construction handbook.
How many Lbs are there in a yard? A pound Lb is a unit of measurement for weight while a yard is a unit of measurement for distance.
If you are referring to common measurements used on a construction site, a yard is a common abbreviation for a cubic yard, which is a unit of measurement of volume. A cubic yard equals 27 cubic feet. Since dirt weighs about pounds per cubic feet, a cubic yard of dirt weighs about Lbs. Since concrete is heavier PCF , a cubic yard of concrete weighs about Lbs. What is a projection line?
Projection line is the way, in which the earth is shown on a flat piece of PAper. What are moment of inertia and its importance in civil engineering? The moment of inertia measures the opposition any kind of body will have against a certain momentum along that same axis trying to rotate that body.
What is the origin of name Railway Sleepers? When sleepers were added below the railway, lines the trains ran more smoothly and people fell asleep on their journeys. Does brick grows bigger every year. Usually bricks do not grow, but since stuff gets all over, it looks like it grows. How did street originate in the plumbing term street ell? A street ell may have gotten its name because it describes a 90 fitting PArticularly useful in tight, street ditches.
When installing water pipes under a street, or from a water service, again under the street, into a home or business, this street ell allows one to change pipe direction with one less fitting, and in less sPAce, than with a standard ell. What is the absolute pressure scale?
Absolute pressure is calculated from a vacuum 0 PSI and atmospheric pressure is What is the difference between QA and QC? Many people and organizations are confused about the difference between quality assurance QA , quality control QC , and testing. They are closely related, but they are different concepts. Since all three are necessary to manage the risks of developing and maintaining software, it is important for software managers to understand the differences.
Note that the process of executing a system includes test planning prior to the execution of the test cases.
How did the Romans get water up hills using aqua ducts? Technically, the Romans were not able to get water to move uphill in a general sense.
All aqueducts move water from an elevated source spring-fed streams in the mountains to end-users at a lower elevation. The water flows almost entirely downhill from the source to the end user. If the water needed to cross a valley, the Romans would build an arched structure with an elevated channel to cross the valley, but even this channel would have a vary slight downhill gradient that allowed water to flow towards the end user.
If a large hill was in their way, the Romans would either divert the channel around the hill, dig a trench through the hill, or dig a tunnel through the hill, all while maintaining a fairly constant, slight downhill gradient towards the end user. The only exception to the rule of a generally constant downhill slope to the water channel is that specific tunnel segments, the Romans could build the tunnel as an inverted siphon mentioned above to cross a depression or valley and raise the water level on the downhill side almost to the level of the uphill side.
To do this requires a well-sealed tunnel strong enough to withstand the increased water pressure within the siphon. Note, however, that except for gaining a little bit of elevation if you slow down fast-moving water, you normally cannot get water to flow out of the outlet at a higher elevation than the inlet.
So technically, even the Romans were not able to get water to flow up a hill. Will Water damage concrete? As far as only concrete is concerned i. The defects that water seePAge induces in concrete are as follows: a induces capillary formation due to the detiorating characteristics of water b With this capillaries the concrete starts sPAlling out; i. It also reduces the pH of the concrete when in salty water or when exposed to marshy areas.
How do you determine Specific gravity of cement? Cement is usually downloadd as a powdery substance that is mixed with sand, aggregate, gravel, and water to form concrete. Since the cement itself is usually a powder, it is hard to measure a standard value for its specific gravity.
At the same time, the engineer's expertise must shine. I believe that my patience, knowledge and sincerity will help me during these interactions with clients. This is a great way to gauge whether the applicant is aware of the latest trends in the industry. What to look for in an answer: A honest person will readily admit that there are challenges in all jobs Look for work ethics that reflect the company's values Listen for clues in how the applicant would resolve the conflict Example: "In my opinion, the biggest challenge that civil engineers face is dealing with clients who want to take shortcuts in order to get the job done on time.
Persuading the client that taking shortcuts is not only unethical but can also be dangerous is sometimes a difficult task. It is imperative to gain their cooperation in order to protect the integrity of the company so that it remains a viable leader in the industry. This answer shows what would be the main priority to the applicant and displays how well he or she is aware of the most important job qualifications.
What to look for in an answer: Look for an answer that reflects the company's values and mission statement Listen for sincerity as the applicant discusses the priority Watch for hesitancy. An honest answer typically is easy for the applicant to formulate if he or she has given the matter much thought. Example: "I believe that protecting the health of the public and environment should be utmost in the mind of civil engineers.
In doing so, they also protect the reputation and respectability of their employer. This answer gives the interviewer insight into the character of the applicant and lets you know if the applicant is right for the job. You see these marked when a contractor calls the Call before you dig number a couple of days prior to excavating.
This is required by law in each state to reduce the likelihood of damaging underground utilities when excavating. White Here is the area I plan on excavating! These are called blue-top stakes. Unlike other fields of engineering, the major advancement of the filed has been in the early years of the century before the last century where the use of concrete technology is advanced. The use of cement as a construction material is since the turn of the last century, improvement in the field increase by the use of steel elements in the construction of buildings and bridges of various types.
With the help of two, it was possible to do multistory buildings in the world. Machineries were created to speed up the construction structures. The last century has also seen the advent of sophisticated design to withstand the effect of earthquake that was not possible before. With the use of computers, development of model and analysis of structures under the effect of loads was made possible.
Before just two decades, it used to take months and months to design high-rise building and big bridges. Now it is a matter of hours. Copper is a very durable material when exposed to weather and is soft enough that it can be easily molded to curved shapes such as those in the Statue of Liberty. It is also traditionally used in buildings for complex roofs, so there would have been trades people available trained to use it.
Are cruise ships built for the transatlantic run? The Queen Mary 2 was built for transatlantic crossings, but much smaller ships can make the crossing easily. Just about any seaworthy Passenger ship can navigate the Atlantic safely, if not comfortably. When a dam is to be built, a diversion tunnel is usually bored through solid rock next to the dam site to byPAss the dam construction site.
The dam is built while the river flows through the diversion tunnel. What distance in meters on the ground is the equivalent of one second of arc in longitude or latitude? One minute of arc as measured at the centre of the Earth covers one nautical mile on the surface of the Earth at mean sea level. One nautical mile is feet or Lines of latitude are at regular intervals PArallel to the equator. The relationship between degrees of latitude and the distance sPAnned on the earths surface remains constant.
Therefore at all latitudes 1 minute of latitude sPAns 1 nautical mile on the earths surface. Lines of longitude converge at the poles. Therefore, the relationship between degrees of longitude and the distance sPAnned on the earth s surface is reduced as the poles are approached.
At the equator, the distance sPAnned by 1 minute of longitude would be 1 nautical mile. At the poles, it would be zero. To calculate the actual distance on the surface of the earth between two points of known latitude and longitude requires knowledge of spherical trigonometry to calculate the great circle distance between the two points. The distances quoted are for the surface of the earth at mean sea level. Distances will be increased above sea level and reduced below it.
If you have water pressure and wish to maintain it, do not cause flow in the line, which will reduce pressure due to friction. To keep pressure up, reduce friction by increasing the line size or eliminating some other restriction. Actually, drying is not directly linked to hardness in concrete. After concrete is poured, putting it in a wet environment by spraying it constantly with water will hasten its hardening and its curing.
After concrete cures, it is hard. Gold mines in South Africa go a few kilometers below the surface. The depth of the mine is well over m from the surface and is getting deeper. The lift itself descends m to a point m below sea level. It takes 4 minutes. When the kg are at rest, on Earth with gravitational acceleration 9.
What does civil engineering mean? They do many interesting things. Their job has to do a lot with design and construction. They can tell you what works and what will not for all sorts of situations.
There is a lot of mathematics involved along with many other disciplines. They have to have a good solid understanding of how the environment works and how nature interacts with man made. They are probably best known for designing bridges, interstates, skyscrapers, canals, and so forth. Pretty good if the outside hose is a lot lower than the inside hose. The siphon works by a hose stuck in a fluid container higher than the receiving container.
Suction is shortly placed on the lower side of the hose until the fluid is flowing down the down line. Gravity will cause a continued flow. StrengthSteel is very strong FlexibilityAbility to flex in the wind CostInexpensive and fast to build; prefab construction Concrete, a possible alternative, has less compressive strength than steel. The bottom support structure of the empire state building would consist of a large percentage of solid concrete simply to support the weight of the building.
For nominal Mix Cement consumption for M25 will be kg per cum. What is the difference between shear and tensile strength? Tensile Strength for a Bolt is determined by applying a Force along it long axis.
Shear Strength for a Bolt is determined by applying a Force across its diameter, as it would be loaded in a lug joint. A person will sink in water if he is not holding enough air in his lungs to keep him floating. Therefore, the person weighs more than the amount of water that he will displace.
Who built the sears tower? While he did not build the structure he died in l , there is some evidence the idea was suggested under a different name Illinois Building by Frank Lloyd Wright, one of the few true skyscrapers in which he had a role.
The original design for the Illinois Building would have topped off at 5, Feet! The Swears tower is a quarter of this at most, but there are similarities. The area ratio decreases slowly at first then more rapidly. Not hard to graph this but you will have to write the area of the ellipse in terms of the circumference. It has to do with the design of the bolts.
The reason that head of the bolt is oval. The head of a bolt fit flush into the bar and set in opposing sets is so that a piece of dragging equipment will not shear off all the bolts in a joint but rather the just the nuts one side. As a result, if the hole were not oval on one side there would be no way to tighten or loose the bolts in a joint. There are many gravity dams constructed of comPActed earth. High dams are generally concrete. All dams require a spillway to be safe.
The spillway must be armored. For purposes of civil engineering, an average soil will have a density of about to pounds per cubic foot.
This can vary a little depending upon how well compacted the soil is. In engineering, the code-allowable withdrawal force is zero, because the wood expands and contracts over time and the nail pullout force can reduce to zero. If you are making a spaghetti bridge, bunch it all together in a triangular prism or a big brick and just fill the gaps with Paste.
What is the tensile strength of marble? Tensile Strength, Ultimate 7. For bending use: Modulus of Rupture 0. Yes, many did. The great pyramid and others that have survived did so for a reason. Their shapes made them sturdier over time and were not the first design. Many steppe pyramids were built but were too steep and as the corners eroded, the whole pyramid fell under its own weight. They were built too steep and did not have the base structure as seen in the great pyramid.
If it floats it is less dense than water, Concrete is lbs. It does not float. Aqueducts are built in areas where you have a bunch of motivated end users like a town or group of farmers at a low elevation in need of a more reliable source of water located somewhere fairly nearby at a higher elevation. The aqueduct builders construct a series of canals, elevated channels, and tunnels as required to get the water from the source to the end users.
Some good examples: What does civil status mean? Civil means like, when you do not get on with someone, but only talk when you have to. Alternatively, when you do talk you do not argue. Alternatively, if you are with someone who is of your both friends and family, you do not ruin it for them. Lead is very toxic; its use can result in pollution of the ground and more importantly of water supplies.
This leads to the contamination of drinking water and can cause hazards to human health as well as disrupting entire ecosystems. Because of its toxicity, lead is being bought less and less around the world, which of course results in the lowering of its cost. In addition, lead melts at a relatively low temperature, making it great for solder. However, recently the Chinese have show an interest in downloading mass quantities to manufacture batteries made from a base of lead so the price of this metal may soon rise.
Same as in inches 3. Explain the various stages of the project planning process in construction. First stage could be Briefing and Inception.
It is the same as building a dam on any river. Dams are built to control flooding downstream during the wet season, generate power year round, and provide irrigation in the dry season. They prevent, or slow down erosion, and stop long shore drift.
This, however, can have bad knock-on effects somewhere near. Now days, many columns are used for decorative purposes. A column along with load bearing beams can support a lot of weight.
If you have never used a ice dam melting sock on your roof before, you will find that they provide an inexpensive method for removing roof ice dams and improving your homes heating efficiency.
Roof ice dams are an annoying source of roof damage, leaks, and heat loss in the winter.
The main causes are drip melt from improperly capped warm air vent pipes and poor roof insulation. Laying a ice melt sock onto the roof so it crosses the ice dam and overhangs the gutter, will melt through the snow and ice and create a channel for water to flow down into the gutters or off the roof.
If done properly those ice sickles that form as the snow melts from the edges of the gutters will never appear, they too are a cause of much damage and are dangerous to life and limb.
