Civil Engineering

It depends on the type of beam, the material, whether it is a bridge span or cantilever, the allowable deflection and safety margin needed. We need a lot more data on the application.

10,000 square feet equates to about 1/4 of an acre.

The original Sunshine Skyway Bridge was constructed in 1954, but destroyed in 1980. The new bridge took five years to build and construction took place from 1982-1987.

Better air flow, less chance of stoppages quietier systems

It is a disadvantage that the same reason Hay's bridge was created is the same reason it is not suitable for measurement of quality factor (Q<10) for Q<10. An advantage is that it is simple expression of the unknown inductor for high quality.

Cement when mixed with sufficient quantity of water,the compounds present in cement reacts with water to form a cementitious crystalline structure that adheres to the sand and aggregates.This helps in binding the mass together and increases its strength till it becomes very hard.This is called hardening of cement.

pips are generally cylindrical in structure of amount of heat loss through pipe is given by the formula Q= 2 pi k L(T1-T2)/ln(r2/r1) where k=conductivity of material of which pipe is made T1= temperature of inside layer pipe T2=temperature outside layer of pipe L= length of pipe r1= inner radius r2=outer radius ln=natural logrithem pi=22/7 the above condition applies for steady state flow,single layer over cylinder and neglecting conductivity convection to take conductivity convection into account term Q* must be added Q*=2 pi L{ r1 hi(Ti-T1)+r2 ho(T2-To)} hi=convective coefficient for inside layer ho=convective coefficient for outside layer Ti= temperature of inside space of pipe To=temperature of outside space of pipe for unsteady condition there is another formulaa

Civil Engineers design things like bridges, large buildings, walkways, monorails, etc.. Basically they solve engineering problems that deal with high amounts of stresses (high amounts of weight, tension or compression, etc.).

from my experience (texas and PA in 2005) and Canada 2012. An entry level Geotechnical engineer should be 45 to 60K a year USD in US and 60 to 70 CAD in Calgary. after 5 years of experience in Calgary a Geotechnical engineer could be making from 85 to 95k a year with a top of 100 k for regular engineer after 10 years of experience and 100k Plus (up to 130k) for good practicioners. hope this helps

It depends on the construction, how complicated it is. Some simple bridges may be built in less than a year, others may take 4-6 years.

as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m.

the steel weight is actually calculated, as a % of the cross-sectional area.

different applications have different minimum % steel required, roughly work on 1%.

the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.

The density of Steel St37 is 7.7 to 8.03 Ã?1000 kg/m3. Steel st37 is used for all types of forging.

1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.

The Millau Viaduct is located in southern France. The architects were Norman Foster and Michel Virlogeux. Construction began on October 16, 2001 and it opened on October 16, 2004.

Curb-To-Curb Width: 14.6m (47.9ft), Out-to-Out Width: 28.0m (91.9ft).

There are two general types of land surveying: plane and geodetic.

Plane surveying considers the earth to be a flat surface--a plane, which works well for jobs spanning a short distance (a few miles), because calculations are relatively simple. Surveys of this nature account for much of survey work being done.

Geodetic surveying takes into account the true shape of the earth. These surveys are usually of a very large scale and most often performed by government agencies. GPS is capable of automatically giving geodetic positions (within certain qualifiers), though a thorough understanding of the principals of geodesy is necessary to adequately design and conduct a geodetic survey.

as per ACI , the ratio between column & beam concrete grades dont exceed 1.4

33.36 psi

the best way to get strong is to eat vegetables and main important is green vegetables

green means u can eat vegetables but the color have to be green
