Civil Engineering

It is called Tower Bridge.

Or you might be talking about the one that was on Harry Potter and the Half-Blood Prince, which is the wobbly bridge, but it's proper name is the Millenium Bridge.

One of the factors that determine whether water infiltrates is the nature of the surface. Another factor that determines is the elevation of the surface or its shape.

One cubic metre of concrete weighs 2.5 Tonnes.

Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water.

Sometimes i ask myself, "why m i so smart ?" :)

Lol, just kidding

Civil engineers had average yearly wages of $78,560 in May 2008.

According to a 2009 survey, people with a bachelor's degree in civil engineering started at $52,048 a year on average.

Your soo Welcome !!

Formula for steel bar weight per meter = D2/162 where D is diameter of bar

Liquid asphalt has a specific gravity range from 0.98 to 1.02. Typically, a specific gravity of 1.0 is used. This can vary with the type of asphalt and the temperature of the asphalt. A specific gravity of 1.0 is the same as water measured at the reference temperature of 60 degrees Fahrenheit. This specific gravity of 1.0 corresponds to a density (or specific weight) of 1 gram per cubic centimeter (1 g/cm3) or 62.4 pounds per cubic foot (62.4 lb/ft3) or 8.34 pounds per gallon (8.34 lb/gal)

A truss is an arrangement of structural members that are connected together to form a rigid framework. In most trusses, members are arranged in interconnected triangles.

A truss is also a medical term for a male hernia support.

Advantages: Very sturdy, can have several cracks in structure before breaking

disadvantages: best for short distances, not attractive, hard to maintain

Grade 60 has a tensile stress of 60000 psi while Grade 40 has 40000.

Grade 60 steel rusts faster than grade 40.

grade 60 bar can be identified by the word 60 which should have printed on that while on grade 40 no no will be printed or written and we can identify this by counting the lines on steel as well.

If there are 3 lines longitudinally on the bar its is of 60 grade and if 2 lines longitudinally it will be identified as 40 grade.

volume of steel multiplied by7850= wt of steel in kgs.

Please note that wt of 1 Cum steel is 7850 kg

Volume of steel bar can be calculated = cross-sectional area of bar X length

cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)

Both of the fields are equally prospective and good. However the field of Civil Engineering is quite rewarding and interesting. Civil Engineering has contributed many rewarding projects to the society development and requires more skills to join in.

Yes. Any of the engineering majors are challenging as they require extensive math, physics, and other science related classes. It takes a lot of dedication and hard work to become an engineer. That is why they are paid better than other 4 year degrees.

It also depends on your hardwork, motivation and interest.

By the way, we have the tallest bridge that supports cars to go over it, but Colorada beats us with being the tallest bridge(not a bridge that supports cars). New River Gorge Bridge is still a better bridge though ;3.

If you mix cement ,sand and water you get mortar If you mix cement and stone pebbles or chips you get concrete Concrete.Sometimes gravel is mixed with it, too.

402 kN at rupture

A characteristic strength is the strength of the material used for design purpose, and is statistically defined by the lower 5% fractile of a bell curve. Compressive strength is a generic term that could refer to anything

Groundbreaking for the George Washington Bridge began in October 1927. The upper level of the bridge was finished on October 24, 1931, while the lower level was finished a little more than 30 years later, on August 29, 1962.

Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.

heat escapes from 2 major places, your head and your feet, the padding on your feet trap the heat in your feet, while the hair are your head traps the heat from escaping there

short column get failed due to crushing force only while long column got failed due to bending moment as well..

It is a continuous pulse of light aimed in a specific direction (as opposed to multiple directions, or in all directions, example being the sun)

the use of the word "continuous" beforehand is like saying "straight ruler" or "circular circle", it's unnecessary unless you need to be sure the person you're telling it to needs to understand, if it is for an assignment or something, then keep it in, if not, take it out.

Hope I helped.

The Truss bridge was invented in the 1980s
