Egyptian Obelisk – St. Peter’s Square

Vibrant Rome – Photo 1 of 6

The Ancient Romans have been strongly influenced by the obelisk form, to the extent that there are now far more than twice as many obelisks standing in Rome as stay in Egypt. All fell soon after the Roman period except for the Vatican obelisk and were re-erected in distinct areas.

Re-erecting the obelisk had daunted even Michelangelo, but Sixtus V was determined to erect it in front of St Peter’s, of which the nave was but to be built. He had a complete-sized wooden mock-up erected inside months of his election. Domenico Fontana, the assistant of Giacomo Della Porta in the Basilica’s building, presented the Pope with a tiny model crane of wood and a heavy tiny obelisk of lead, which Sixtus himself was in a position to raise by turning a little winch with his finger. Fontana was provided the project.
The obelisk, half-buried in the debris of the ages, was first excavated as it stood then it took from April 30 to Might 17, 1586 to move it on rollers to the Piazza: it needed nearly 1000 males, 140 carthorses, 47 cranes. The re-erection, scheduled for September 14, the Feast of the Exaltation of the Cross, was watched by a big crowd. It was a well-known feat of engineering, which created the reputation of Fontana, who detailed it in a book illustrated with copperplate etchings, Della Trasportatione dell’Obelisco Vaticano et delle Fabriche di Nostro Signore Papa Sisto V (1590),[ten][11] which itself set a new regular in communicating technical details and influenced subsequent architectural publications by its meticulous precision.[12] Before getting re-erected the obelisk was exorcised. It is stated that Fontana had teams of relay horses to make his getaway if the enterprise failed. When Carlo Maderno came to build the Basilica’s nave, he had to place the slightest kink in its axis, to line it precisely with the obelisk.

Outsource Your Wind Turbine Design, CNC Precision Engineering and Welding Fabrication Tasks

Outsource Your Wind Turbine Design, CNC Precision Engineering and Welding Fabrication Tasks

What do wind turbine style, CNC precision engineering and welding fabrication have in common? Properly, if you are an OEM or Original Equipment Manufacturer, then you must have guessed that it is the reality that all these tasks demand a high degree of accuracy and finesse. Additionally, they need to have committed resources in the kind of manpower, cash, space, time and tools. The slightest mistake could result in shoddy work that does not pass muster with your personal high standards as an OEM, let alone with your consumers.

 

Even so, you may be constrained by present circumstances from allocating the sources needed to total these tasks perfectly. You may not have the requisite skilled labor, or the additional factory space, for instance. Economic limitations might stop you from hiring the labor and expanding your manufacturing facility. What then must you do?

 

Trying to total the tasks on your own in such situation is foolhardy you will either finish up with less than satisfactory wind turbine design, CNC precision engineering and welding fabrication, or you will finish up delivering right after the project deadline. In both circumstances, your reputation will suffer and you could lose company. It would consequently be savvier to outsource these jobs to a contract manufacturer who specializes in such tasks, and get the advantage of their expertise.

 

There are numerous good contract makers out there who can supply you great turbine design, as properly as the most current CNC engineering and welding fabrication. Many of them have decades of experience in these regions, so you can rely on them to offer you only the very best manufacturing solutions. They take care to employ only the very best specialists and the newest tools to execute these jobs. As a outcome, they can offer you you delivery properly just before project deadlines. So in sum, these contract equipment manufacturer and designers save you from the hassle of trying to full your manufacturing jobs with restricted resources, they enable you to get reliable and timely services, lessen your to-industry time and in the end enhance your position in the industry.

 

But perhaps the greatest advantage supplied by these contract companies is the cost savings they offer you. As they offer their manufacturing at lower than market rates, you can get bigger profit margins when you outsource these jobs to them. The time and resources saved by outsourcing your work can be far more productively utilized elsewhere, to expand your organization or to increase consumer relations. This will support you get more company, and a lot more profits.

 

Due to the fact of all these above offered motives, you must not hesitate to outsource your manufacturing perform to contract producers if the need arises. It could be the ideal company choice you ever make.

1965 – 1976 Lancia Fulvia Coupé

Image by Georg Sander
The Lancia Fulvia is an Italian auto introduced at the Geneva Motor Show in 1963 by Lancia. It was made by that company by means of 1976. Fulvias are notable for their role in automobile racing history, including winning the International Rally Championship in 1972. On testing it in 1967, Road &amp Track summed up the Fulvia as &quota precision motorcar, an engineering tour de force&quot.

(Wikipedia)

– – –

Der Lancia Fulvia ist ein Automobil des italienischen Herstellers Lancia. Es wurde von Herbst 1963 bis Ende 1976 gebaut und gilt als Nachfolgemodell des Lancia Appia.

Wie andere nach dem 1950 vorgestellten Aurelia entwickelten Lancia-Modelle war der Fulvia nach einer klassischen Römerstraße, hier der Via Fulvia, benannt. Im Herbst 1972 wurde dieses Method der Benennung wieder geändert: der unter Fiat-Regie gebaute Nachfolger des Fulvia war der Lancia Beta.

Der Fulvia war als Berlina (Limousine) und als Coupé erhältlich. Außerdem gab es wie bei Lancia üblich ein bei Carrozzeria Zagato entworfenes und in Kleinserie gebautes Fließheckcoupé mit dem traditionellen Namen Sport. Das technische Konzept des Fulvia stammt von Antonio Fessia, die Type wurde von Pietro Castagnero bei Lancia entworfen.

Materials in Mechanical Engineering

Materials in Mechanical Engineering


by tom$

Engineering components, in principle, may be divided into four main classes:

Metals
Ceramics and glasses
Polymers and elastomers
Composites

Supplies belonging to a single of these classes exhibit comparable properties, processing routes, and most typically applications as well. The criteria for the material choice are rather complex and depend on the intended application goal. To the principal design and style criteria belong strength, stiffness, fracture toughness, formability, capability to join, corrosion resistance, and coefficient of thermal expansion, price, and final but not least the capacity to recycle.

Iron-primarily based materials are the most widely employed metallic materials, primarily simply because of their comparatively affordable manufacturing and their massive flexibility. Accordingly, the properties of Fe-primarily based components can be varied to a great extent, allowing precise adaptation to particular application specifications ranging from higher-strength, high-temperature, and put on-resistant alloys for tools to soft or hard ferromagnetic alloys for applications in the electrical industries. Pure iron, even so, is only of minor significance in structural applications given that its mechanical properties are just inadequate. Alloying with carbon leads to the most crucial groups of constructional alloys, namely:

1. Steels with a carbon content material of up to about 2.06% carbon (if not stated otherwise all compositions are giving in wt. %)

2. Cast iron, which virtually consists of 2.5–5% carbon.

Ceramic and glass materials are complex compounds and solid options containing metallic and nonmetallic components, which are composed either by ionic or covalent bonds. Standard properties of glasses and ceramics include high hardness, high compressive strength, high brittleness, higher melting point, and low electrical and thermal conductivity. There are several methods in which ceramics may possibly be classified, such as by chemical composition, properties or applications. Polymers (polymer components, polymeric components, strong polymers, and macromolecular materials) consist of quite massive molecules (chain molecules, macro molecules) which are synthesized from little molecules (monomers, monomer units) by a chemical reaction named polymerization. The polymerization reactions can be classified into four groups.  Chain polymerization proceeds by the reaction of a monomer unit with the reactive website at the finish of a polymer chain. These are mainly reactions by way of a radical mechanism. The terminus condensation chain polymerization is utilized in circumstances exactly where a low-molar-mass byproduct is formed during polymerization. In polycondensation currently generated polymer chains react with each and every other or with a monomer unit whereby a low-molar-mass byproduct is generated. Elastomers (rubber-like polymers) consist, similarly to thermoplastics, of linear molecules, but the molecule chains are bridged by modest-molecule segments via covalent bondings. The molecules can therefore undergo a robust elastic deformation at area temperature. This effect is due to the stretching of the molecules out of the disordered state if a load is applied, and a re-deformation into the random tangle of molecules due to the enhanced entropy, right after the load is released. Composite supplies are formed when two supplies which belong to various material classes are combined to attain properties which are not supplied by the original components. Achievable combinations are:

Metal–ceramics
Metal–polymer
Ceramic–polymer
