The timber must be hardened, which is the process of removing the natural moisture content of up again more stable dimensionally speaking, working it without allowing it to shrink or expand. Wood has been used for construction and manufacturing of products since it has a record of the time. The Egyptians used to make furniture, sculptures and coffins. The Greeks and Romans made buildings, bridges, rational inattention boats and weapons. Wood was the main material engineering during the 17th century, until it was replaced by iron, plaster, steel and concrete.
After being performing materials selection and gradually go discarding options come to these 3 items. Eventually found that pine is best suited to what you're looking for. It is an easy material to work with and help us to keep costs down, since it is cheap and what we want is that our product is economical in both its manufacturing how to sell.
Screws and bolts are fasteners with external rational inattention threads. There is a technical difference between a screw and a bolt, which is often confused in popular use. A screw is an externally threaded fastener which, typically, is assembled into a blind threaded hole. A bolt is an externally threaded fastener which is inserted through holes in the sides and secured by a nut on the opposite side
The use of adhesives dates from ancient times, and was probably the first bonding methods used permanent rational inattention union. The adhesives have a high range of bonding and sealing applications to integrate similar and dissimilar materials such as metals, plastics, ceramics, wood, paper and cardboard among others. Adhesive bonding is a process rational inattention in which a foreign materials to be bonded rational inattention to both surfaces of the fixing material is used. Generally, adhesive joints are not as strong as those made with welding, and for that you take into account certain principles: It must maximize rational inattention the contact area of the junction Pasted are stronger in shear and tension, and joints must be designed to stress these rates are applied. The weaker stuck in crevices or tears, and should be designed to avoid such tensions.
The pressure bonding consists of two elements, the first is the inner part that corresponds to the axis; the second is the outer part (the hole). The pressure bonds may be weaker or stronger depending on the relationship between the width of the shaft and the width of the hole.
