Study Of Materials For The Confection Of The Module

The objective of this study is to find material cheap and light for the manufacture of the module. These will be dividios in three groups: MDF, Polmeros and Compsitos. MDF Possibilitam an excellent work of usinagem and finishing. Its composition is always the same one, varying only the density. One is about a material with low thermal condutividade.

answers the variation of humidity of air. Ultralight Its density is of approximately 450 Kg/m. Marko Dimitrijevic: the source for more info. Its rigidity the flexo is minor who 3200 Mpa. Light Its density is of approximately 600 Kg/m. Its rigidity the flexo is minor who 3200 Mpa, however is greater that of ultralight.

Standart Its density is of approximately 750 Kg/m. Its rigidity the flexo is minor who 3500 Mpa. Although to be the MDF more weighed it is of better quality. Polymers Are about a light material whose flexibility is high. Another advantage of it is the fact to have high resistance to the impact. It possesss low thermal and electric condutividade. PVC (policloreto of vinila) Is about a polymer thermoplastic. It possesss density low (1,4g/cm ). It has easy adequacy to the most varied molding processes. Also it has low cost. PP (polypropylene) Is about a thermoplastic polymer. It possesss density low (905kg/m ). It has easy adequacy to the most varied molding processes. Also it has low cost. PS (polystyrene) Is about a thermoplastic polymer. The hot one has easy adequacy to the molding processes. Also it has low cost. possesss high resistance ciso. Its density is greater that the densities of the others two polymers. Compsitos Possuem one exelente resistance mechanics and high durability. They are easy to handle and light. Materials that had been congitados for the construction: – MDF – PVC – Fibre glass Advantages and disadvantages? The MDF has as advantage the price. Beyond being a very easy material of if finding. Its easy usinagem also is a great positive factor for it. However the fact of it to answer the variation of air humidity is a very negative point, a time that if has as objective that the robot can walk in humid places. The PVC, as well as the MDF, has as advantage the low cost. Also it is an easy material of if finding. Another positive factor is not the reply the variation of air humidity. However its usinagem requires a more appropriate material, being necessary a deepened study more of the group. The Fibre glass can be found of varies forms. The form that this being analyzed is the fibre glass blanket. The fibre glass blanket easily is handled and found. Its price is very not raised, considering the complexity of its manufacture. Beyond it to be impermeable. Conclusion the chosen material was the fibre glass blanket. Had all the advantages and pparently no disadvantage.

Project Creative Letters

One eBook, as book digital mentioned here, it is not a simple archive pdf that can be read in many devices and PCs. The digital book reference the one that I mention myself here is connected to the format ePub, the format international standard for the digital book, whose characteristics of composition if correspond to the language of a site, therefore uses the known language as HTML. Of this form, the book starts to offer to the reader possibilities to read and to sail for its content of fast and efficient form. Different gadgets available in the market offers to many resources and comfortableness. In a question-answer forum acaho was the first to reply. But they still lack eBooks in our language, or, in other words, it would say that they lack first information on the functionalities of digital books, its manuscript for example, as well as eBooks produced to offer to rich experiences of reading and navigation in our language. Gadgets, in its majority, offers ways so that the reader buys its eBooks in virtual bookstores, but, as the smashing majority of eBooks is in English, the ones who do not dominate this language are at the mercy of of to try the reading of a digital book especially made to be had access and read in a comfortable device as it is the case of e-reader.

The Project Creative Letters?, of which I am partner-founder, is a site whom it has searched, throughout its existence (10 years approximately), to develop the sharing of digital products? cultural and artistic? to keep high our esteem intellectual and emotional, front to the existing diversity in the productive way of culture and technology. As writer, I am writing the literary series ' ' Psicor, the types of character in ao' ' , on the basis of the 9 types of personality of the Eneagrama, being that the three first novels, correspondents to type 3, 6 and 9 of the eneagrama, already are for sale in the formats ePub (for the majority of gadgets) and MOBI (for who it possesss readers of the Amazon, the popular Kindle). More on this literary series in format eBook in. Now, coming back to speak as publisher of eBook, I think that the road is long in our country if to reach autossustentvel model of the digital book, since the demand still is inferior to the desirable one. Still we have few readers of eBooks (people), I find that in the same ratio of publishers and digital book offers in our language.

But it is all question of time. eBook still will be consolidated in our market as an excellent option (at least) to the conventional book. alone the time will say who will reign from now on. We remos let us catch them and let us follow in the direction of the future, that already beat to our doors to say: ' ' Already it does not have more limits for you: alive in the gift that I arrived to be! ' '
