Construction

I got this out of my social studies notebook: (not exactly word for word) "loose construction" is when federalists interpert the Constitution into things that are FOR a stronger National Government. by the way federalists are an organized group of people who are in favor of a strong National government.

The members of the US Congress, as of January 1, 2008, are paid $169,300 per year. Click on the "Congressional Salaries" link below to read about the history of the salaries of the members of Congress, which started out in 1789 at $6 per day.

the brake down is:

365 days in a year each day they are making $463.84

in a 8hr day they are making $57.98 a hour

it has been 219years they have jumped from $6 a day to $463.84 a day

Limit of retention is the maximum amount that can be retained in the construction contract. Suppose the retention % is 5% and limit of retention is 10%. On a contract value of Rs100.00. The first claim amounts to Rs20.00. Retention is Rs1.00 and net payment is Rs 19.00

According to it's construction, stairs are categorized as follows: 1. Brick Stairs:-

- Brick stairs used for external steps & stairs.

2. Stone Stairs:-

- These are very expensive; and are rarely used.

3. Concrete Stairs:-

- These are widely used in all types of buildings. These are strong, fire resistant and make possible a wide range of forms.

4. Timber Stairs:-

- These are economical & lightweight. Commonly used in domestic buildings.

Plank and beam is typically referred to as post and beam. This type of construction is used a large percentage of the time for new home construction. It is used in colder climates more than warmer climates because you have the ability to insulate under the floor of the house. In warmer climates slab floor construction is used more than it would be used in colder climates. There is another type of construction that is used but not as often. It is called the joist system. This is the way Post and Beam construction works. A vertical member (post) is set on concrete pads, about 8 feet apart. The horizontal member(beam) is set on the posts. The spacing between the beams are typically 4 feet apart. The end of the beams are placed in beam pockets that have been designed into the foundation. Then 2"x6" or 2"x8" tongue and grove planks are placed perpendicular on the beams to create the floor. In slab construction you pour a concrete floor between the footing and foundation. A joist system uses 2x material to span between two points and tie into a ledger board using metal hangers. This system is used for decks more often and the 2nd and 3rd floors of homes.

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.

Photovoltaic Cells: Converting Photons to ElectronsThe solar cells that you see on calculators andsatellites are photovoltaic cells or modules (modules are simply a group of cells electrically connected and packaged in one frame). Photovoltaic, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house. How do these devices work? Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon, which is currently the most commonly used. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally. For example, the current can power a calculator. This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce. That's the basic process, but there's really much more to it. Let's take a deeper look into one example of a PV cell: the single-crystal silicon cell.

The question, as stated, cannot be answered sensibly. A cubic metre is a measure of volume, with dimensions [L3]. A tonne is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

A full wave bridge rectifier converts AC (Alternating Current) into DC (Direct Current) with an AC component. To achieve DC only, the output of the bridge rectifier must have the AC component removed by bypassing it, usually with capacitors.

It consists of 4 diodes in a bridge format. During one half of an AC cycle, two of the diodes conduct and on the other half a cycle the other two conduct. Diodes allow current to flow in one direction only.

The reason for workers to prefer volume batching in general construction is that volume batching which involves measuring the volume of the ingredients (cement, coarse and fine aggregates, etc.) is easier, simpler and faster, whereas weigh batching involves tedious work- transporting the mixtures to weighing machines,weighing; if it exceeds the desired amount, it has to be unloaded etc. And moreover labourers at work sites are not technical and hence they tend to ignore complicated processes. If I am at work site I would do the same, though I'm an engineer.

Sand and gravel are dug out of open quarries on the surface.

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.

Industrial construction is building for non residential use, primarily for commerce or business.

The area to be concreted is sectioned off is small section across and up the incline. The hardcore base is fully compacted to prevent movement. The mix is made and is put into each section and allowed to go off before removing the horizontal board at the bottom of the concreted section. In most cases an additive is used to make the mix set quicker than normal thus preventing running. In the case of large areas (i.e. sides of roads, etc.) they actually used a preset slab which is lifted into place and has expansion joins inset to cope with heat changes in the concrete.

What is the main components usually is concrete

yes

contact shin caterpillar company whom would be the one who supplies the Mitsubishi engines, go through the company listing of products as supplied to other manufactures and you should be able to track where and what they were supplied for in the way of equipment.

Visit http://www.diamonddiesels.co.UK/engref.HTML where you will find references and links to the various Mitsubishi engine types that are used by construction equipment manufacturers

Sidewalks are made of concrete, which is not a rock. Concrete is a man-made construction material composed of Portland cement, various crushed rocks, sand and water.
