Bowden cables can cease to function smoothly, particularly if water or contaminants get into the housing. Modern lined and stainless steel cables are less prone to these problems; unlined housings should be lubricated with a light machine oil. In cold climates Bowden cable mechanisms are prone to malfunction due to water freezing.
The SAE discussed an increased automobile standard voltage as early as 1988. [3]In 1994, at the initiative of Daimler-Benz, the first "Workshop on Advanced Architectures for Automotive Electrical Distribution Systems" was held at the Massachusetts Institute of Technology Laboratory for Electromagnetic and Electronic Systems (MIT/LEES) in Cambridge, Massachusetts USA. with the aim of defining ...
A pooled analysis found consistent evidence of an effect of ELF-MF on childhood leukaemia. [23] An assessment of the burden of disease potentially resulting from ELF MF exposure in Europe found that 1.5–2% of childhood leukaemia cases might be attributable to ELF MF, but uncertainties around causal mechanisms and models of dose-response were ...
A DOT-111 tank car, specification 111A100W1, constructed by fusion welding carbon steel.This car has a capacity of 30,110 US gallons (113,979 L; 25,071.8 imp gal), a test pressure of 100 psi (690 kPa), a tare weight of 65,000 pounds (29,500 kg) and a load limit of 198,000 pounds (89,800 kg).
A loudspeaker is composed of a permanent magnet, copper wire, paper, etc. Everything that can be identified as a homogeneous material must meet the limit. So if it turns out that the case was made of plastic with 2,300 ppm (0.23%) PBB used as a flame retardant, then the entire radio would fail the requirements of the directive.
The furry gray mammal is cute, but the habits of squirrels (and other rodents) can cost hundreds to thousands of dollars in car repairs. Squirrels love chewing car wires. Here’s why — and how ...
Equipotential bonding is done from where the distribution wiring enters the building to incoming water and gas services. It is also done in bathrooms where all exposed metal that leaves the bathroom including metal pipes and the earths of electrical circuits must be bonded together to ensure that they are always at the same potential. Isolated ...
A farm in the mountains of Norway stands on the site of what was once a “large and powerful Viking farm” and has yielded a significant Viking treasure.
