ABSTRACT

The search and research for science and truth have yielded more than enough results for justice rights. The static stress-strength relation is characterized by the “Mohr-Coulomb” criterion with formula: ? = c + ? tan(?), where c is the cohesion and ? the internal frictional angle of the rock, ? and ? are the shear and normal stresses on the failure plane. It includes the two-part static strength of cohesion plus frictional resistance due to confinement. The Chinese PinYin of “Mohr-Coulomb” means “wood relies on agriculture and forest”. Rock Fracture toughness testing has revealed the mechanics of cohesive strength in the fracture process zone. Bicycling reveals the work and power of frictional force. The ancient kinetic experiment of falling solid revealed the energy conservation and balance formula. Falling solid impact testing and monitoring of supporting steel rod revealed the XYZT Xing Guang matter energy nearly elastic system vibration and wave propagation unity as well as reversibility and revolution theorem. This science and technology peak was achieved in 1991 to 1993 with the aid of a 286 data acquisition computer and a 286 laptop computer with DOS Turbo C programming language.

One can roll one egg to hit two adjacent eggs in contact and watch the third egg to go off. This is a quasi-static dynamic experiment to experience the stress wave propagation and ejection phenomena. It is not difficult to imagine that big explosion or impact on earth can affect the diametrically opposite side of the earth, especially the inner surface of the whole earth. Burning of pine resin inspires one to apply Einstein’s matter energy equation, and seismic wave theory and rockburst or blasting mechanism would suggest energy equation modification to accord with the kinetic energy formula and estimation of light wave peak particle velocity. The effects of seismic waves can be related to the effects of visible and invisible waves. Various ground support methods can be related to earth support matters and systems. It is easy to realize that water and tree ecosystems help move the earth, and invisible electromagnetic waves and visible light waves maintain the revolution of the solar system (ref. Issac Newton Motto: If given a stick and a fixed point in space I can move the earth).

Small earthquake provides enough information about its cause and effect. Combination of windy rain and earthquake shake has caused significant effect and even disaster at some places where human works have weaken the ground or created conditions for secondary disaster, such as fire. Man kind must not obstruct the smooth movement and revolution of the earth. The bamboo flute cracking in dry air and healing under water shows clearly the material has the ability to change forth and back to a certain extent in response to the system. Rock and joints are subject to seasonal change and change due to its system change. Man made machine, such as the time watch, is at best a quasi-eternal machine. Computer artificial intelligence comes at the price of gold from the crustal core of the earth. The shrinking orebody at less than 2000 m depth indicates a very thin rock crust as compared to earth diameter. Several factors indicate that the earth is empty inside. Since compressive wave and tensile wave can change into one another, and rockmass tensile strength is nearly zero, it can be prudently concluded that the impact strength of earth is nearly zero.

An ecosystem can be everlasting system. Since the suname man stands somewhere between the valley stone water grass fish and the mountain cloud tree bird, the intelligence of material, ecosystem and earth have long been recognized by the rights surname man. The traditional manual comprehensive agriculture has proven throughout the ages to be always the essential eternal justice rights.
