A billet is a length of metal that has a round or square cross-section, with an area less than 36 in 2 (230 cm 2). Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. [1] [2] [4] Billets are further processed via profile rolling and drawing. Final products include bar stock and wire. [3]
His was the first modern ball-bearing design, with the ball running along a groove in the axle assembly. [1] Jules Suriray, a Parisian bicycle mechanic, designed the first radial style ball bearing in 1869, [2] which was then fitted to the winning bicycle ridden by James Moore in the world's first bicycle road race, Paris-Rouen, in November ...
The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field.
The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity is the theoretical maximum pressure which can be supported without failure; allowable bearing capacity is the ultimate bearing capacity divided by a factor of safety.
A load-bearing wall or bearing wall is a wall that is an active structural element of a building — that is, it bears the weight of the elements above said wall, resting upon it by conducting its weight to a foundation structure. [1] The materials most often used to construct load-bearing walls in large buildings are concrete, block, or brick.
This can yield time savings of up to 40% compared with traditional solid slabs. [1] However, this is heavily dependent on the particular system, and systems relying on onsite placement of void formers requires much more labor than solid slabs. [2] Compared to one-way hollow-core slabs, biaxial slabs are more resistant to seismic disturbance.
Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a colourless, volatile liquid. It is a colourless, volatile liquid. Purified trichlorosilane is the principal precursor to ultrapure silicon in the semiconductor industry.
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
