What is pH test in civil engineering?
In the field of water supplies, it is a factor that must be considered in chemical coagulation, disinfection, water softening and corrosion control. In waste water treatment processes pH must be controlled with in range favorable to particular organisms. All these processes are controlled by environmental engineers.
Can the Yield strength of steel ever be greater than the Ultimate tensile strength?
The yield strength is reached when the material becomes non - linear ( that is non elastic) and takes a permanent set when load is released. Material stretches but does not break. Ultimate strength is when it breaks and is higher than yield strength.
What is the basic salary of civil engineer?
The yearly salary of a person who works in civil engineering solely depends upon your position in which you are working. If you are a beginning engineer your average salary is about $58,590 (rounded). Anywhere from there the salaries go from $71,400 up to $112,790 (all numbers are rounded to come out to whole numbers).
Is biotechnology a medical subject or an engineering subject?
Biotechnology could combine both subject matter from medicine and from engineering. Biotechnology is based in biology. But it is often used to refere to genetic engineering. Biochemistry, organic chemistry or chemical engineering can play a part in biotechnology. A link is provided to the Wikipedia article on biotechnology. Surf on over and just read the first paragraph and see what kind of picture you come away with.
Where is the stepped strip foundation used?
A stepped strip foundation is often used on a sloping site where the steps allow the foundation to follow the slope without too much excavation, when compared with excavations and retaining walls. A floor structure that spans between perimeter strip foundations , whether over intermediate piles or not, also minimises excavation, when compared with a slab on grade or slab on fill floor.
How do you make a scale model of a roman temple?
You can make it with alot of things, be creative! You could use Styrofoam, you could use wood, or simple household items! Sugar cubes stick together great when fluff is used as the cement, you could make it out of that! It's up to you!
What are the most recent invention in civil engineering?
I do not know what exactly the question mean? If you are talking about major advancement in the fiield since the turn of the last century or the recent advancement i.e over the last 5 years or so?. Unlike other fields of engineering, the major advancement of the filed has been in the early years of the centuiry befor the last century where the use of conrete technogy is advented. The use of cement as a construction material. since the turn of the last century, improvemnet 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 muti storey 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 earth quake that was not possible before. With the use of computers, development ofmodel and analysiss of structures under the effect of laods was made possible. Before just two decades, it used to take months amd months to design high rise building and big bridges. Now it is a matter of hours .
- Cement having much higher strength than that of ordinary portland cement.
- Lithium salts are used as accelerators to increase the early strength.
- Strength of 4 MPa has been obtained within 1 hour and 27 MPa in 3 hours and 49 MPa in 1 day.
What are the required skills to be a civil engineer?
Must be able to travel extensively to work sites. Must be very exact in their work. Errors could create serious safety hazards for users of the structures they design. Make decisions that strongly impact their coworkers and company. Meet strict deadlines weekly. Can make most decisions and set most tasks without consulting a supervisor. Work both indoors and outdoors. Are sometimes exposed to contaminants when working on environmental projects. Are sometimes exposed to very hot or cold temperatures when visiting job sites. Often work around hazardous equipment such as excavators, cranes, and drill rigs. Often work from a van or car while at project sites. Sometimes work inside a building without heat or air conditioning. Have a moderate level of social contact. They work half of the time with other engineers and department staff, but spend time alone analyzing data and planning designs. Are often placed in conflict situations. Clients and engineers may disagree over the direction of projects. Deal with unpleasant, angry, or rude people monthly. Are greatly responsible for the work done by others. This is especially true for engineers when they sign final plans and reports. Work with a team that may include other engineers and scientists, field staff, and clerical staff. Communicate daily with coworkers by telephone and in person.
Write letters, e-mails, and reports weekly.
What does the civil engineering squadron provides in the US air force?
Construction and maintenance of the base's infrastructure
What are the advantage of consistency concept?
- Easier to understand (saves time so money)
- Users know what to expect.
- Generates trust an reliability to customers.
What is the strength of concrete after 28 days?
The compressive strength of M25 concrete at 7 days will be between 6-7.5 N/mm2 .
What are the materials needed to make a beam bridge?
Beam bridges are the most simple of structural forms being supported by an abutment at each end of the bridge deck. No moments are transferred throughout the support hence their structural type is known as simply supported.
The simplest beam bridge could be a slab of stone, or a plank of wood laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete used can either be reinforced, prestressed or post-tensioned.
Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses, or box girders. They could be half-through, or braced across the top to create a through bridge. A footbridge using beams over a stream in Dordogne, France
Because no moments are transferred, thrust, as from an arch bridge, cannot be accommodated, so leading to innovative designs, such as lenticular trusses & bow string arches, which contain the horizontal forces within the superstructure.
Beam bridges are not limited to a single span. Some viaducts such as the Feiyunjiang Bridge in China have multiple simply supported spans supported by piers. This is opposed to viaducts using continuous spans over the piers.
Beam bridges are often only used for relatively short distances because, unlike truss bridges, they have no built in supports. The only supports are provided by piers.
What is the effect on velocity and pressure if a liquid flows in a convergent pipe?
I think velocity is directly proportionate to its applying pressure.
How many credits do you need to get a bachelors degree in civil engineering?
In general, for colleges that operate on a two regular semester academic year, the amount of credits needed to complete a Bachelors Degree can run anywhere from 124 to 128. The important issue here is that these credits must be applied to a specific program of study as prescribe by the institution. If the credits are not appropriately applied, it does not matter how many credits an individual accumulates, they still will not have a degree, but just an accumulation of credits. Viper1
- Consistency means amount of water needed to prepare a plastic mix.
- Consistency test is done using Vicat's appartus.
- Consistency of cement should be less than 30%
- consistency test is used to find the amount of water to be mixed with cement.It is necessary to find the consistency because amount of water present in the cement paste may affect the setting time.standard consistency is indicated by the vicat plunger reading (5 to 7) from the bottom of mould(IS 4031 (part 4)1988)
How did the tacoma narrow bridge fail and break into pieces?
The original Tacoma Narrows Bridge that was opened in 1940 collapsed due to heavy winds. The roadway twisted and vibrated violently under 40-mile-per-hour (64 km/h) winds on the day of the collapse.
What is the tallest structure in Alabama?
Famous landmarks in Florida include Disney World, Kennedy Space Center, Epcot, Everglades, Florida Keys, Busch Gardens, and LEGOLAND. Other famous landmarks are Gator Land, Florida Aquarium, and Bok Tower Gardens.
What is the difference between the singly reinforced beam and doubly reinforced beam?
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
