B. import both sweaters and machinery from Britain. C. export sweaters to Britain and import machinery from Britain. D. import sweaters from Britain and export machinery to Britain.

D. import sweaters from Britain and export machinery to Britain.

Q:A certain piece of machinery depreciates from 9600 to 8160 in one year. What percent decrease is it?

Amount depreciated : 9600 - 8160 = 1440 Percent depreciated : 1440/9600 * 100 = 15%

Q:new developments in marine machinery?

I'm sorry, could you phrase that in the form of a question?

Q:I'm interested in investing in candle lantern manufacturing because of low competition in my local area but I'm not sure where to start and what equipment would be needed to start manufacturing on low scale. Is there any good read on how are lanterns recycled and what additional equipment would be needed to recycle them? Please go into as much details as possible.

From my understanding, most of these candle lanterns are hand- made.

Q:as for cars, the battery is recharge when the engine is running, but when fully charged, it automatically shut off. Where are the excess electricity going?we used to have frequent power interruptions here in our locality. So, whenever there is electric power.We connect some car batteries to a power regulator/dynamo installed to an industrial machine that should operate constantly. But having the electric power back on normal operation, the owner didn't bother harnessing this energy bcuz they say it was inconvenient.Is that typical of humans?

Astonishingly, the solutions you have available to you are generally the most efficient that are available at the time. We're naturally lazy creatures, so we do as little work as possible to get the solution we want... thus also being as efficient as we can be. Knock yourself out on this one, but you'll soon see how silly it is.

Q:Why is it impossible to develop machineries without electronic wave?Why do all machineries do require electronic wave?

There are machines that are completely mechanical, no electrical parts. Electricity is used to provide the energy to do the work that the machine does.

Q:For example if i lost my arm or someone loosing there leg. Do you think technology will ever come to a point that they will replace it with some machinery; which will it seem as it were my normal arm.

I agree with Maria. It will most definitely come to pass. The biggest obstacles right now are the nervous system, and understanding how it issues commands to the body. Most current technologies use muscle triggering. For example, all of your muscles work together. If you move one part of your body, muscles in adjoining body parts tense up in specific ways to help counter momentum to give you better control. Using those facts, scientists can design body parts that read and respond to those trigger movements. It's not perfect, but it does work to an extent. To be true limb-replacement, the nervous system will need to be better understood.

Q:Engineering machinery as the main means of project construction industry in recent years (including construction machinery, road construction machinery) and demand has increased rapidly, which stimulates the use of the manufacturing, engineering machinery, maintenance industry often demand. At the same time, the high-tech construction machinery, maintenance equipment maintenance maintenance numerous, complex process, high technical requirements and related mechanical engineering research and development, manufacturing, sales, use, maintenance and other personnel, enterprises generally reflect the lack of.

The profession is very good, employment is particularly easy, and if you do not hate physics, it is not so hard to learn. This year, the school is not circulated a piece of it, a large enterprise to recruit machinery students, the boss said: "you just do not have a diploma, as long as there are student cards, we want you.". It shows that employment is fairly good, but the fact that wages are not particularly high is a fact. For example, when you enter a bank, you can take 5K months, and the machines may look like 2K to 3K.

Q:I just entered an abandoned air traffic control room, that have been abandoned since 1998 and I saw these stuff in it, Does you know what are they and the usage??

The first few pics It seems like a storage tank, like fuel tank The second pic looks like some engine, however it could well be some microwave magnetron or TWT tube parts of some assembly. The pics with text you can translate that on Google language tools, works very well (most of the time!) Then it is some video game Hope this properly answers your question Guru

Q:Mechanical drawings, stiffeners, cutaway, right?

Section and section map, the internal structure is based on the graphic illustrations according to certain cutting direction display, profile is imaginary tangent plane of the object with a cut section, remove between the observer and the cutting plane is the part between the projection map for the remaining part of the projection surface. The profile generally used for the design of mechanical parts and engineering drawings in the supplement and complete design documents, detailed design engineering design drawings and mechanical parts, used to guide the construction and operation of mechanical processing.
