Why is a lorimerlite structure the strongest under compression?
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.

It depends on the kinds of stresses the structure is expected to resist. To resist cantilever stresses (bending - a combination of compression, tension, and sheer), the octet-…truss is the strongest possible structure. To resist only tension a straight line, such as a cable, is the optimum structural geometry; and to resist only compression a lorimerlite framework is the strongest structural geometry.
The structure in which waste material is compressed is called the rectum. This is short tube that is at the end of the large intestine.
in a structure like a building an arch is the strongest in a simple geometric structure a sphere would be the strongest because there is not week point such as a corner
the strongest bones are your femur (thigh bone) and id say your spine would be next.

ask your mom she knows
wich material is the strongest in compression?
The octet-truss is the strongest structure for cantilevering loads, however lorimerlite structures are strongest when holding loads under only compression.

The proper location is about two fingers width below the Xiphoid process (the peice of cartilage between the ribs.) This is more between the ribcage and not below it.
A cylinder, a sphere or a dome.
In terms of tensile strength it's the hexagon, as used in the construction of carbon nanotubes.
Think of it this way, unquestionably the strongest structure is a solid. But now the compromises begin: Is weight a factor? Is material cost a factor? Does it need to be hollo…w? Once these parameters are known, then the loads must be determined. Are the loads static, dynamic, vibratory, etc. Are the loads in shear, torsional, moment, cantilever, etc. Do we need to consider earthquake, thermal loads, or impact loads? And we must look at the desired building material(s): steel has the same strength in all directions (isotropic, wood, concrete, and composites are wildly non-isotropic so the direction of the loads becomes important. Take the case of a sky scraper. We must consider the shape of the occupied area as well as all the necessary load cases. Thus we end up with a square girder structure which is not the strongest perhaps, but is adequate and meets all the other requirements. Considering bridges, for short spans the basic AASHTO concrete girder and deck is extremely durable and strong as well as cost effective. For longer spans we look at arcs of structural steel which are extremely strong and beautiful, or cable suspension/cable stayed designs using concrete piers that can withstand hurricane force winds. The Eiffel Tower was built for the International Exhibition of Paris in 1889, but despite the age, it remains one of the worlds most brilliant examples of construction. Some key observations: 1. Notice that it is open, the structural elements are exposed. This reduces wind loads (routinely 100 MPH at the top!) and saves cost.2. Notice the arches combined with the "X" structural shapes. Arches are very efficient material wise, the "X" prevents buckling.3. Notice the width at the base. This is an amazingly stable and strong structure.4. Steel (actually puddled or wrought iron in this case) members can be rapidly assembled. This required 300 workers for two years. A bargain!5. Super lightweight: it has been said that a 1 foot high scale model would only weigh as much as a nickel!
