Angle of repose

The angle of repose, or critical angle of repose,[1] of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the ...

The concrete cone failure load of a single anchor in uncracked concrete unaffected by edge influences or overlapping cones of neighboring anchors is given by: N 0 = k f c c h e f 1.5 [ N ] {displaystyle N_{0}=k{sqrt {f_{cc}}}{h_{ef}}^{1.5}[N]},

90,000 year-old specialised bone technology in the Aterian …

 · The question of cognitive complexity in early Homo sapiens in North Africa is intimately tied to the emergence of the Aterian culture (~145 ka). One of the diagnostic indicators of cognitive complexity is the presence of specialised bone tools, however significant uncertainty remains over the manufacture and use of these artefacts within the Aterian techno-complex. In this paper we report on a ...

Cone

 · In South Africa, mine drifts excavated in high stress rock are typically supported with energy-absorbing rockbolts (e.g. cone bolts and Durabar) and ductile bolts (e.g. split set and cables). The primary bolting method is a ring of 1.2-m long bolts and the secondary bolting is a ring of 2.4-m long bolts plus lacing, meshing and 50 mm thick steel or polyester fibre shotcrete ( Fig. 9 ).

Forcing cone angles | Single-Actions

 · The low angle must then be cut deep to provide forcing cone with enough root diameter to avoid spitting. Thus, a narrow-angle cone of, say, 5-degrees, works best with minimal chamber offset. While a cylinder loose on its pin gives the bullet more chance to align passage from throat to bore.

What If the African Continent Broke Apart?

 · Well, it''s possible, and it''s happening to Africa right now. In 2005, a 60 km long stretch of the continent cracked open over a period of just ten days, and it hasn''t stopped expanding since. Eventually, the landmass will break right off, giving birth to a brand new ocean.

Hyperbola

In mathematics, a hyperbola (adjective form hyperbolic, listen) (plural hyperbolas, or hyperbolae ()) is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution set. A hyperbola has two pieces, called connected components or branches, that are mirror images of each other and resemble two infinite bows.

Volcanic cone

Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones ...
