Primary loading

With binary copper—lead, the continuous copper phase provides the primary load support while pockets of 20—50% lead supply a continuous lead surface film. Tin content of 3—5% is commonly incorporated with the lead to minimi2e corrosion. Copper—lead alloys, either cast or sintered on a steel back, provide good fatigue resistance for heavy-duty main and connecting rod bearings for auto, tmck, diesel, and aircraft engines. 

However, synthetic wood is not a one-for-one structural replacement for wood in all applications. Moreover, it is not intended for use as columns, beams, joists, stringers, and other primary load-bearing elements. 

Sealed Friction Bearing (Journal Bearing). The Journal hearing, developed to match the life of carbide cutting structures, does not contain rollers hut contains only a solid journal pin mated to the inside surface of the cone. This Journal becomes the primary load carrying element for the cone loads. 

Performance tests on current and voltage transformers to verify ratio and polarity. These may include the injection of current into the primary load circuit (primary injection). 

Material behavior have many classifications. Examples are (1) creep, and relaxation behavior with a primary load environment of high or moderate temperatures (2) fatigue, viscoelastic, and elastic range vibration or impact (3) fluidlike flow, as a solid to a gas, which is a very high velocity or hypervelocity impact and (4) crack propagation and environmental embrittlement, as well as ductile and brittle fractures. 

All structures, regardless of how simple the construction, posses more than one degree of freedom. However, many structures can be adequately represented as a series of SDOF systems for analysis purposes. The accuracy obtainable from a SDOF approximation depends on how well the deformed shape of the structure and its resistance can be represented with respect to time. Sufficiently accurate results can be obtained for primary load carrying components of structures such as beams, girders, columns, wall panels, diaphragm slabs and shear walls. 

StructurPly I and II by Multi-Axial are thermoplastic matrix resin prepregs used in the construction of primary-load-carrying composite structures. Unlike the few hours typically required by the thermoset resin materials to cure, StructurPly needs a few minutes at 196°C. 

The time step implemented in the simulation tools is of the order of a few minutes up to one hour. It is also assumed that the time series of primary load and...

The concurrent introduction of both Lucifer Yellow and Rhodamine dextran (which emits red fluorescence with a spectrum distinct from that of Lucifer Yellow) into cells allows the identification of the primary loaded cells, and thus serves to control that Lucifer Yellow transfer into neighboring cells happens via gap junctions.

There are generally two levels of concentrations. These are primary loading— a large concentration that is used to achieve a fast therapeutic effect such as the first dose of an antibiotic, and maintenance dose—a typical concentration of the dmg that is used to provide an ongoing therapeutic effect such as subsequent doses of an antibiotic. 

Primary loading is the first measured quantity of drug that is eliminated from the body. 

A tire is a textile-steel-rubber composite the steel and textile cords reinforce the rubber and are the primary load-carrying structures within the tire. Because of the performance demands of fatigue resistance, tensile strength, durability, and resilience, seven principal materials have been found suitable for tire application cotton, rayon, nylon, polyester, steel, fiberglass, and aramid the latter three materials find primary usage in the tire crown or belt region. 

Ablative TPSs are not applicable to large reusable spaceplanes because their consumption would change the aerodynamic profUe, jeopardising the flight control, and their replacement after each mission would cost too much. Therefore two basic concepts have been developed for primary load-carrying structures of spaceplanes ... 

The primary loads considered in the design of reinforced-concrete structures which must serve to ensure, with a high level of confidence, that systems or components they house can fulfill their lOCFRlOO-related radionuclide control functions under design basis conditions are as follows ... 

Fibre reinforced materials are indeed very versatile. In addition to their use in primary load carrying structures, they have been used as repair materials for structural components made from composites and metals. This chapter highlights several examples which demonstrate the relative ease with which repair to structural components can be achieved with fibre reinforced plastics. It is also pointed out that, as with other materials, the designer of any repair scheme with reinforced plastics must be aware of the effects of the environment on the performance of the materials used. Although fibre reinforced plastics are used in corrosive environments, studies in the Gulf States have shown that severe temperature fluctuations can affect the performance of fibre reinforced plastics in a repair environment.
