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 buying 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.

Ponding is not preferred for curing as this method of thermal curing is greatly affected by cold winds. In addition to that in ponding large amounts of water is used and has to be disposed off from the construction sites. Polythene sheets are used on the basis that it creates an airtight environment around the concrete surface henceforth reducing the chances of evaporation over fresh concrete surfaces.
But the usage of polythene can be a drawback as it can be easily blown away by winds and also the water lost by self-desiccation cannot be replenished. Answer : Slump tests are performed to empirically measure the work ability of fresh concrete. It is used to measure the consistency of the concrete.
In general there are three different types of slumps that occur in slump tests. They are as follows: True Slump: This type of slump is characterized by the general drop of the concrete mass evenly without visible signs of deterioration or disintegration.
Shear Slump: It indicates that the concrete mix is deficient in cohesion. This type of slump leads to segregation and bleeding. Henceforth in the long run effecting the durability of the concrete. Collapse Slump: This type of slump is indicates that the mix of concrete is simply too wet.
The mix is considered to be harsh and lean. Answer : Once the process of concreting is performed the striking of the formworks should be done as soon as possible as delay in this process can lead to the discoloration of the concrete structures.
In case of long structures particularly long span structures once the structures have attained enough strength to support themselves it is essential to provide them with propping as creep deflection can take place which can greatly reduce the integrity of the structure.
Due to the above mentioned reasons propping should be done after the removal of formwork. Also the props should not be made to stand long as it can lead to overstress for the structures.
1.What are the causes of building collapse?
Answer : The formation of air bubbles in a fluid due to low pressure conditions lower than the saturation pressure is known as cavitations. This is considered to be a high potential damage condition where the strength and durability of the pipes can be greatly reduced. Cavitation works on the principle of Bernoulli's Equation. When fluids are at high velocities the pressure head of fluids reduce accordingly. But since the fluid pressure is lower than the saturation pressure the dissolved gases get released from the flowing fluid.
Civil Engineering Interview Questions
These air bubbles suddenly collapse on entering a region of high pressure. This leads to the damage of the pipelines as a high level of dynamic pressure is created. Answer : Beddings are primarily made up of granular or concrete materials.
They are primarily used for the following purposes: They are used to provide a more uniform support for the under pipes so that the bending moment longitudinally can be reduced greatly. In order to enable the pipes to get more load-supporting strength.
They are also used to act as a platform to achieve a more correct alignment and level pre and post construction. In case of pipes which contain spigot and socket joints, it enables pipes to get supported along pipe lengths in place of sockets.Define What is passive earth pressure?
Now it is a matter of hours. How do you interact with clients? This is so as there is noticeably not much improvement in the transverse load distribution when the number of cells of the box girder is higher than three or more. But the presence of the metal plates does not affect the shear stiffness of the bearings.
Also the usage of elastomeric bearings leads to the uneven distribution of stress on the piers. The display of your dimensions can be turned off in CAD for that you have to go under Floor Plan View and follow the following steps. Vivek Dubey.
The area ratio decreases slowly at first then more rapidly. A more useful question is What is the typical density of concrete?
