Wind turbines have been around for 124 years.
It has been around from 1888 - 2012.
Texas and California are the leaders in wind generation in the United States.
Where to give lap in bottom reinforcement of beam?
It depends on the stress/load applied to a beam, but a general rule is to provide a lap where the stress is the least. In a simply supported beam with a uniformly distributed load the best place to position laps would be away from the centre of the beam.
What is the yield stress of a twisted bar as compared to an ordinary mild steel bar?
Tensile yield strength in a steel bar is the amount of pressure exerted before the bar begins to bend. Tensile steel is used for a variety of construction projects.
What classes do you need to take to earn a bachelor's degree in history?
This depends on the school and the kind of degree sought. If you are an English major, expect to take a lot of English classes. If you're an engineer, engineering classes. Contact the schools you're interested in and see if they can forward you their degree requirements for the schools you're interested in.
It depends of what type of bridge you want to make. A big one or a small one. I tell you how to make the small one. The best, I think, you should use triangles for you bridge, no matter the material is wood or metal.

What is the angle of internal friction for clay?
Till is a term describing an unsorted sediment of varying composition. It consists of several different grain sizes and can contain different amounts of clay. As the angle of internal friction is based on the cohesion and grain size of the material the answer is that it varies depending on the composition of the specific till.
Fine grained material used in cement?
The fineness of cement has an important bearing on the rate of hydration and hence on
the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a
greater surface area for hydration and hence faster the development of strength.
What is water to cement ratio?
- Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.
- Strength of concrete primarily depends upon the strength of cement paste.
- Similarly, the strength of the paste increases with cement content and decreases with air and water content.
The term Gateway Bridge may refer to any of the following structures: * Gateway Bridge in Brisbane, Queensland, Australia * Gateway Bridge over the Mississippi River in Clinton, Iowa * Gateway Bridge in Brownsville, Texas * Thames Gateway Bridge is a proposed new crossing of the River Thames in East London

What is an example of a shear strength?
scissors
garden shears
something like that........
also a zipper
----------------
If you were to use 1 word it to describe Shear Force it would be Twisting. So basically things like:
Laffy Taffy
Pretzel
The game of Twister
Twisting a lock of hair
Tornadoes
Tendons/Muscles doing sports
What is the difference between ms bar and tor steel?
One type of steel is worked when cold, and the other is treated when hot.
TOR steel is technically a brand name for reinforcing steel from Toristeg Steel of Luxembourg.
TOR has become a verbal shortcut for any type of CTD (Cold Twisted Deformed) steel. It is one form of HYSD (High Yield Strength Deformed) steel.
TMT steel bar is a newer variety of steel for construction purposes. For many years TOR Steel has been used for concrete reinforcement. Thermo Mechanically Treated bars (TMT bars) give you several advantages over the other types of steel:
Twisting operation is not involved in the production of the TMT steel bar,so no residual stresses involved in that , which in turn increases the corrosion resistance.
Rust and Corrosion Resistance :
The main reason for failure in any reinforcement concrete structure is due to corrosion of TOR Steel in the concrete, where this steel corrodes in existence of chloride ions. TMT Bars, due to its Thermo- mechanical treatment are very highly rust and corrosion resistant and is best suited in the humid and coastal states like West Bengal and Orissa.
Uses:
TMT Bars are much superior to conventional TOR Steel by virtue of their various engineering properties and can be used for Residential Buildings, Bridges, Drums, Industrial Establishment and all types of concrete reinforcement purposes.
TMT Bars:
Grade - Fe 415
IS: 1786
Note:
The project designers use thermo mechanically treated bars (TMT) in place of torsteel and even in TMT, the choice is increasingly focused on that with higher tensile strength ( Fe-500 in lieu of Fe-415) and high corrosion resistant TMT (HCRM) which is specially meant for use in coastal areas.
Groynes are placed so as to reduce coastal (or riverside) erosion.
In the coastal case, they interrupt the flow of sediment along the coast, and accumulate it alongside the groyne. They are only temporary, though with a life of decades.
Riverside groynes rely upon their mass to prevent current erosion of the riverbank. They will not usually accumulate sediments in any great quantity.

Filter press is intermittent operation equipment, it has plate and frame one, chamber one and vertical one. Here Zhengzhou Toper company will introduce which industries filter press is used.
The main purpose of filter press is solid-liquid separation, compare with other separation equipment,the cake after filter press has lower cake moisture and good effect. Solid-liquid separation principle is, press device press the plates to form filter chambers, liquid-solid mixture get into the filter chambers, with the pressure, liquid get through the filter cloth and flow out, but solid retained in the chambers to be cake.
Filter press is the common separation equipment in mining, food, chemical and so on industry, and early used in chemical industry of 18th century, and now it is widely used in chemical, pharmaceutical, metallurgy, dyes, food, brewing, ceramics, and environmental protection industries. Totally now filter press is in the rise phase, and almost every industry, you can find filter press.
If you need filter press in the future, get back with us!

Some examples of Roman Architecture in US?
Some examples of Roman architecture are the arch, the dome, the atrium and the Composite ad Tuscan styles of columns.
How much does a 8 inch hollow concrete block weigh?
well the density of concrete can vary from 2200kg/m3-2800kg/m3 but 2400kg/m3 is the most common
Quantity of cement in Mix M30 concrete?
There is no fixed rule for this. If manual mix, cement content shall vary between 350 ~ 400 Kg / M3.
Where as for Design mix (RMC), the cement content is decided by the supplier based on lot of other parameters and achieve the desired strength in 3, 7, 15 & 28 Days. Also PFA (Portland Fly Ash) shall also be added to some extent to arrive the desired strenth. The Cement & Fly Ash content shall be 300 / 80 kg per M3, to achieve the desired strength.
Why are pillars there on a arch bridge?
To spread the force being exerted on them from the weight they hold up over as wide an area as possible to help prevent damage
What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
