Technical Articles - Know Your Parts Google+ Facebook Twitter YouTube It's What's Inside That Counts Menu What parts system category do you need most? Earthbag Construction EarthBag Homes - you're standing on the building materials... earthbag home Long sandbags are filled on-site and arranged in layers or as compressed coils. Stabilizers such as cement, lime, or sodium carbonate may be added to an ideal mix of 70% sand, 30% clay. Belt friction In practice, the theoretical tension acting on the belt or rope calculated by the belt friction equation can be compared to the maximum tension the belt can support. This helps a designer of such a rig to know how many times the belt or rope must be wrapped around the pulley to prevent it from slipping. Mountain climbers and sailing crews demonstrate a standard knowledge of belt friction when accomplishing basic tasks. Equation[edit] The equation used to model belt friction is, assuming the belt has no mass and its material is a fixed composition:[2]

Learn Lua the Hard Way This series more or less mirrors the series of the same name for Python. It’s in my belief that the only way to learn the in and outs of a language is to learn by practice, and by that virtue, to practice as often as possible until you get the hang of the language. 1. Other Tutorials Chapters 6–10 → The Table Tutorial.Chapter 11. The project team problem part 1

O-ring Typical O-ring and application The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. Manufacturing[edit] O-rings can be produced by extrusion, injection molding, pressure molding or transfer molding.[1] History[edit] Welding Zinc Coated Steels: New Joint Design and Strategy with Scanner Technology « Laser Insights By: Klaus Loeffler, Dr. Tim Hesse, Peter Kaupp TRUMPF Laser und Systemtechnik GmbH, Ditzingen, GermanyTRUMPF Werkzeugmaschinen GmbH, Ditzingen, Germany Siemens STEM - Grades 9,10,11,12 NASA Videos Promethean Resource Pack This resource pack contains six videos from NASA's Glenn Research Center in Cleveland, OH.

Fluid bearing They can be broadly classified into two types: fluid dynamic bearings and hydrostatic bearings. Hydrostatic bearings are externally pressurized fluid bearings, where the fluid is usually oil, water or air, and the pressurization is done by a pump. Hydrodynamic bearings rely on the high speed of the journal (the part of the shaft resting on the fluid) to pressurize the fluid in a wedge between the faces. Fluid bearings are frequently used in high load, high speed or high precision applications where ordinary ball bearings would have short life or cause high noise and vibration. They are also used increasingly to reduce cost. Gravitational Vortex Power Plant is Safe for Fish While trying to find a method for aerating water without energy input, Austrian engineer Franz Zotlöterer stumbled across the idea of a mini-power plant which is simple to construct and has a turbine efficiency of 80% but which is safe for fish due to low turbine speed and improves water quality by oxygenation. Needless to say, he quickly applied for the patents. The technology can be applied with water drop as little as 0.7 meters. Zotlöterer's website suggests an idyllic installation along a modern stream that has had its meanders rudely obliterated in the interest of human civilization.

From Flange to Butt Joint: Lasers in Auto Production (EuroPhotonics Dr. Rüdiger Brockmann and Peter Kaupp, Trumpf Laser-und-Systemtechnik New concepts in the design and construction of structural elements such as beams, sills and car doors that include the use of profiles, single-sided laser joining processes and interlocking connectors save weight, time, costs and installation space. These new concepts lead to simpler construction techniques such as using butt joints instead of overlapping flange connections, and joining that doesn’t require special clamping devices. How much material, weight and fuel can be saved if the flange and lap joints on beams, sills, tunnels and other welded open channel constructions of a car body are replaced with butt joints?

 Rolling and Plain Bearings Bearings for rotary motion are designed as rolling bearings or plain bearings. A distinction is drawn as to whether the forces occurring between the parts movable relative to each other are transmitted by rolling or sliding elements. Rolling bearingsRolling bearings generally comprise two bearing rings with integral raceways.
