The No.14 Chair made by German-born cabinetmaker Michael Thonet is one of the most bestselling consumer products of the nineteenth century (Doick‚ 2009). It was the world’s first industrially produced bent-wood chair and the first mass produced chair (Doick‚ 2009). First introduced in 1859‚ the No.14 Chair is regarded as an iconic product‚ “which although no one has ever actually done the math‚ is thought to have seated more people than any other chair in history” (Rawsthorn‚ 2008). The No.14 Chair

Most structural steel failures happen at connections....where a beam connects to a column‚ where a joist connects to a beam‚ where a hanging rod connects to a beam (the Kansas City Hyatt discussed above). The Structural Engineer must design the design the steel members and give guidelines for the connections. Many people in the Construction Industry don’t understand‚ though‚ that the Structural Engineer rarely designs the connections. Why is that? Historically‚ the Steel Fabricators developed

(SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion. The diagram above shows a beam carrying loads W1‚ W2 and W3. It is simply supported at two points where the reactions are R1 and R2. Assume that the beam is divided into two parts bya section X-X. The resultant of the loads and reaction acting on the left of A-A is vertically upwards and since the whole beam is in equilibrium‚ the

Hypermobility syndrome is a condition that features joints that easily move beyond the normal range expected for a particular joint. Hypermobility is also known as “double-jointness”. This particular disorder has an unknown discovery date and founder. The causes of hypermobility are family history: disorder is inherited‚ bone structure‚ muscle structure and sense of proprioception which is knowing how far you are able to stretch. Genes that are responsible for the production of collagen are suspected

spreads out as it travels‚ so as the distance from the source increases the amount of light hitting any given area actually decreases. A Laser light is different. It has a very constricted beam that remains solid and concentrated over a distance as much as 2‚500 feet long. Laser light travels as a parallel beam and spreads very little. When using grading

Cars need to be maintained frequently in order to stay healthy. Your vehicle needs your attention more often than most people realize. Some people don’t even know the least little thing about maintaining a vehicle. Your vehicle is basically a weapon if used incorrectly and if you don’t maintain it there’s a greater risk of hurting yourself or others. I will go through some of these maintenance methods in full detail‚ the methods I will be discussing are fluids‚ air filter‚ and oil. Preventative

Phototropism is a growth movement induced by a light stimulus. Growth towards a source of light is called positive phototropism‚ that away from the source is termed negative phototropism. The tips of shoots are usually positively‚ that of roots negatively phototropic. Originally (with J. v. SACHS‚ for example) was phototropism called heliotropism‚ because the plant grows towards the sun. The name was altered when it became clear that plants react also towards artificial sources of light (W. PFEFFER)
