Civil Engineering

I believe a bridge should be considered a simple machine. It saves work and gives mechanical advantage. It can also shorten distance, so unlike an inclined plane it can benefit without increasing distance. It can bypass the need to raise and lower massess into crevasses, it can bypass long journeys down then back up a hill. I could find no discussion anywhere.

The concept of enterpreneurship development refers to the creation of a wide pool of personal business initiatives designed to provide a variety of services or goods as the demand may be.

Enterpreneurship development has a positive impact on the economy of any country especially developing ones. Enterpreneurship development encourages creativity and self reliance. It ultimately relieves Government of the burden of social dependence.

For an engineer job you have to consider writing your extraordinary skills that make you a perfect communicator or link between engineers, contractors, clients, and management.

Your resume should also showcase your creative ideas, your technical skill, your awareness to latest technology, and your imaginative methods to improve efficiency.

To get some samples of civil engineers resume, see the related link below.

Safe construction practices are rules that should be followed for the safety of those on a construction site. Proper footwear and headgear must be worn at all times. Dangerous areas should be clearly marked or roped off. Equipment must be properly stored and turned off when not in use.

The material of choice is stainless steel, because of its cost, abundance, strength, and reliability.

Strip foundations are used to support a line of loads, either due to a load-bearing wall, or if a line of columns need supporting where column positions are so close that individual pad foundation would be inappropriate.

That is approximately 5,300 pounds.

Stressed concrete beams have a variety of uses in civil engineering. They hold up roofs and bridges among other things. -These concrete beams are not just concrete, they have steel cables inside that create a tension to make the beam stronger.

M5 concrete is a mix with a nominal ratio of 1:5:10, consisting of one part cement, five parts sand, and ten parts aggregate (gravel or crushed stone). This mix typically yields a compressive strength of about 5 MPa (megapascals) at 28 days. M5 concrete is primarily used for applications that require low strength, such as bedding for pipes, footings for small structures, and other non-structural elements. Its purpose is to provide a cost-effective solution for projects where high strength is not critical.

The concept of reinforcement was given by Edward Thorndike in his theory of Connectivism/ Connectionist theory of learning. He gave three laws - Law of readiness,Law of exercise and Law of effect.

The law of effect in particular talks about reinforcement; "responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce a discomforting effect become less likely to occur again in that situation". Here, the satisfying situation/effect become a reinforcer, positive or negative.

Load bearing capacity of the soil

1 US gallon = 3.78541178 liters. Only if you mean pure water, then 1000 litres of water weighs 1 metric tonne. 1000 litres of water are 264.172052357 gallons that weigh 1 metric tonne.

"Nothing is true, everything can be questioned" but while learning the basics one should not question :(

It takes an engineer to undertake the training of an engineer and not, as often happens, a theoretical engineer who is clever on a blackboard with mathematical formulae but useless as far as production is concerned ;)

Approximately 707-738 kg of sand would be used in 1m3 of concrete.

To see how this is calculated, see below:

To some extent this depends on the type of concrete, however for normal usage you would expect the concrete to be made by using 1 part cement, 2 parts dry sand, 3 parts course stone aggregate and 1/2 part water. NB those are weight rather than volume terms.

As such approximately 4/13ths of the 1m3 mass would be sand. Concrete has a density ranging from 2300 - 2400 kg/m3

As such 4/13ths of 2300 = 707kg

and 4/13ths of 2400 = 738 kg

simply workabilty is the w/c ratio in concrete. more the w/c ratio higher the workability and vice versa. and it is true that excess amount of w/c ratio doesnt give proper strength. so workable concrete i.e, concrete with proper w/c is must for good strength.

*note: not considering the mix of concrete.

There are many companies and websites that offer steel bars for sale. Some of these websites that offer steel bars for sale are ULINE, Bodybuilding and Northern Tool.

because is needs the Ca-OH that is produced from the cement reaction with water to start the hardening but if you added Ca-OH to water it may be used a cement but its very expensive with no much difference in strength

The type of product measured does not change its weight requirement; a ton of feathers and a ton of asphalt all weigh: 2,000 pounds in American and 2,240 pounds in the United Kingdom; systems of measurement.

Yes. An arch bridge is one of the more efficient ways of building and maintaining a bridge. Beam bridges are not as efficient. For a given span and height, an arch bridge will carry a greater load using less material. The beam structures of a beam bridge can be constructed of wood, reinforced concrete or steel (in increasing order of strength). The beams, however, must be supported by piers or an abutment at each end, which can be made out of concrete, masonry, stone, or steel (or combination thereof). The arch structure of an arch bridge can be constructed of wood, reinforced concrete, steel, or masonry, and the arch can be supported by abutments as described above, or the arch can extended down to the foundation itself. The primary advantage of an arch is that stresses caused by the load on the bridge are converted primarily into compressive stresses that are carried along the arch into the ground. Materials like stone, masonry and concrete are particularly good at carrying these compressive stresses. In contrast, loads on a typical beam-type bridge creates large tensile stresses on the bottom of the beams. Since stone, masonry and unreinforced concrete have very little capacity to withstand tension, none of these materials can be used to make a reliable and efficient beam-type bridge of any significant span.

Curing is necessary for freshly cast concrete in order to maintain the moisture as the chemical constituents in cement react with water and heat evolves continuously until the setting process completes.

The heat evolved during the setting of concrete is called heat of hydration, and this heat causes the water to evaporate. Proper and complete setting process is the most important phenomenon that imparts the desired strength to the concrete.

If the freshly cast concrete is not cured, it develops cracks and also the chemical reactions will cease resulting in bad concrete.
