  • This part of BS 5950 supersedes BS 5950-1:1990, which is withdrawn. A period of three months is being allowed for users to convert to the new standard. This edition introduces technical changes based on a review of the standard, but it does not constitute a full revision. This new edition has been prepared following the issue of a number of new related standards adopting European or international standards for materials and processes, plus revisions to standards for loading. It also reflects the transfer of cold formed structural hollow sections from BS 5950-5 to BS 5950-1....

  • Rolling bearings are machine elements found in a wide field of applications. They are reliable even under the toughest conditions and premature failure is very rare. The first sign of rolling bearing damage is primarily unusual operating behaviour of the bearings. The examination of damaged bearings reveals a wide and varied range of phenomena. Inspection of the bearings alone is normally not enough to pinpoint the cause of damage, but rather the inspection of the mating parts, lubrication, and sealing as well as the operating and environmental conditions.

  • Carbon nanotubes (CNTs), discovered in 1991, have been a subject of intensive research for a wide range of applications. Carbon nanotubes have emerged as the main target of many researchers around the world in pursue to the next nanoscale device. CNTs are one-dimensional (1D) graphene sheets rolled into a tubular form and due to their exceptional electrical and mechanical properties, the possible application in a wide spectrum of electron devices is certainly the focus of future research generations....

  • The extension of central bank liquidity eased the pace of asset-shedding observed in late 2011, but did not turn the underlying trend. If the banks in the EBA sample, for instance, failed to roll over their senior unsecured debt maturing over a two-year horizon, which amounts to more than €1,100 billion (€600 billion among banks with a capital shortfall), they would have to shed funded assets in equal measure. By covering these funding needs, the LTROs and dollar swap lines helped avert an accelerated deleveraging process.

  • During the anodic etch, a high acid content, low solution temperature, and high current density will minimize smut formation. Carryover of water into the anodic etching solution should be held to a minimum, and long transfer times after the anodic etch should be avoided. Cold rolled steel that has been subjected to deep drawing and certain prepickled hot rolled steels with glazed brownishcolored surfaces may be exceedingly difficult to clean. For these materials, a solution of 25 to 85 vol% nitric acid has proved effective....

  • Wear Film failure impairs the relative movement between solid bodies and inevitably causes severe damage to the contacting surfaces. The consequence of film failure is severe wear. Wear in these circumstances is the result of adhesion between contacting bodies and is termed ‘adhesive wear’. When the intervening films are partially effective then milder forms of wear occur and these are often initiated by fatigue processes due to repetitive stresses under either sliding or rolling. These milder forms of wear can therefore be termed ‘fatigue wear’.

  • So, in summary, traction is important for transmitting the forces from the wheels to the road. If any of your wheels are spinning rather than rolling, you probably need more traction. Traction can be increased by adding a non-slip material around the wheels (like a tire) or by moving weight over the driven wheels. But, remember, it is also important to have efficient wheels, which are usually thin and lightweight. Bearings When you have two things rubbing against each other and you want them to move freely, friction slows things down and wastes energy.

  • Carbon nanotubes are rolled up graphene sheets with a quasi-one-dimensional structure of nanometer-scale diameters. More than twenty years have passed since the pioneering work on carbon nanotubes by Prof. Iijima in 1991. During all these years, carbon nanotubes have at‐ tracted a lot of attention from physicists, chemists, material scientists, and electronic device engineers because of their excellent structural, electronic, optical, chemical, and mechanical properties.
