Q:I wanna know why is machinery production more effective than labor?
Machines work everyday putting out the same quality of product. Humans can vary everyday with there mood and they could have 3 different shifts come in doing different quality too. Plus when holidays come the humans are off work when the machines are sometimes still running with a skeleton crew operating them. Humans are also more expensive because of wages and benefits and lawsuits when things dont go well for them.
Q:Do you know any large Bulgarian website for selling used things? specifically machinery?
And the list with machines: okorder.com
Q:What boat propulsion machinery is steam driven?
Many modern ships are powered with electric motors. The electric generators are sometimes powered by steam driven turbines, sometimes gas turbines. Some ships have propulsion driven directly with steam turbines. -- Regards, John Popelish
Q:What is the difference between the equipment manufacturing industry and the machine building industry?
Equipment manufacturing, also known as equipment industry, mainly refers to the capital goods manufacturing industry, is to meet the needs of the development of the national economy departments and national security needs and manufacture all kinds of technical equipment industry collectively. According to the national economy sector, its range of products including investment manufactured goods machinery electronics and ordnance industry, belonging to the metal products industry, general equipment manufacturing industry, special equipment manufacturing, transportation equipment manufacturing, electrical equipment and equipment manufacturing industry, electronics and communications equipment manufacturing, instrumentation and cultural office the equipment manufacturing industry in the 7 major categories of 185 kinds.
Q:During 2010 a corporation purchased machinery costing $450,000. This is the only acquisitions of depreciable p?
Sorry, but your question cuts off in mid-sentence and is hence unanswerable. You'll need to add more info in the 'Additional Details' area of your question screen if you desire an answer.
Q:sony or acer aspire ...have an old laptop and really want a reasonable prices sexy piece of machinery?
Acer make an exceptionally super type of laptops for different manufacturers who rebadge them. In my place as customer of laptops, we stumbled on that Sonys have been large for extra or less 18 months, yet in basic terms began to crumple after that. The areas have been far extra costly than different computing device areas, and to get them serviced we had to courier them to France (heavily...) each and all of the Acers we've ever offered (13 on the final count quantity) are nevertheless going stable, a number of them are 4 years old or extra. in case you like kind over substance and a incredible type of preloaded stuff which you do no longer want, decide for the Sony. in any different case, i might % Acer every time.

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.
Q:What are the differences between mechanical components and mechanical parts?
At present, other countries in the world, including international organizations, have not put forward the concept of equipment manufacturing. "Equipment manufacturing" concept can be said of China's unique. Its formal appearance was seen in the central economic work conference in 1998, which explicitly stated: "we must energetically develop the equipment manufacturing industry.""
