Why is a lorimerlite structure the strongest under compression?
ThomasJeal
In architecture and engineering a lorimerlite structure is a lightweight support framework made up entirely of tetrahedral joints (four beams meeting at 109.5 degree angles). Lorimerlite structures are used to withstand compressive loads with the least amount of structural material. This is achieved through the inherent geometry of the support system; for a predefined volume of space to fill and predefined number of joints in the structure, each beam finds the shortest unbraced path through space (in the same way as a hexagonal grid in two dimensions). The smaller the length of individual beams the greater the resistance to axial compression, reducing the danger of lateral buckling and thus enhancing the compressive strength of the entire structure. Loads are distributed at each joint evenly with every beam meeting at 109.5 degree angles.

Which bridge is the strongest truss or suspension and why?
lorimerlite frameworks are the strongest for resisting compression, however octet-trusses are much stronger when resisting cantilever stresses
Describe how the conditions under which rocks form affect the physical stability of rocks.?
The conditions that affect physical stability are heat, temperature, compression, pressure, and the molecular structure.
The part of a wave where molecules are pressed close together is under?
Compression
What kind of fault moves because it is under compression?
Reverse faults move due to being under pressure.
Are alkali metals gasses?
all of them are solids (under room temperate, and room compression)
Which bridge is the strongest truss or suspension and why?
lorimerlite frameworks are the strongest for resisting compression, however octet-trusses are much stronger when resisting cantilever stresses
What is the second strongest geometric shape?
It really depends on what kind of strength you are looking for, a triangle is the strongest shape when rigidity is what is needed (so when you want to have a strong cantilever structure or a general structure that can resist a variety of stresses). It's difficult to say what might be the second strongest shape in such circumstances, but maybe a triangle that is not equilateral, but this is an over simplification. An octet-truss is the strongest structure for cantilevering because of the strength of the triangle However if its 'hardness' you're looking for, or resistance to purely compression, a tessellation of hexagons is your strongest shape, and therefore perhapse an irregular hexagon is your second strongest. A lorimerlite framework is the strongest truss under compression because of the strength of hexagons.
When building a structure what is the strongest load bearing angle?
"Vertical, with zero declination for loads under compression;" no intention to flippant, but more information is needed about the structure or load for a useful answer to be tendered. If the structure is intended to hold liquid or gas the strongest structure may spherical, etc.
Stone slabs are stronger under compression or tension?

Is it tension or compression that strengthens an arch that supports the load?
compression: the keystone in particular is under rather high compression forces.
Is an arched roman bridge under compression or tension?
it is under compression since both sides are being pushed towards each other.
Why is concrete in compression and weak under tension?
Concrete is strong in compression, as the aggregate efficiently carries the compression load. However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete solves these problems by adding metal reinforcing bars, glass fiber, or plastic fiber to carry tensile loads
