Hooking Theory

Further details can be found in several texts including those on the theory of particulate processes (Randolph and Larson, 1988), crystallization (Van Hook, 1961 Bamforth, 1965 Nyvlt, 1970 Jancic and Grootscholten, 1984 Garside etal., 1991 Nyvlt, 1992 Tavare, 1995 Mersmann, 2001 Myerson, 2001 Mullin, 2001) and precipitation (Walton, 1967 Sohnel and Garside, 1992). 

This is called Avogadro s theorem (1811) it appears here simply as a definition of molecular weighty and this is really the manner in which the relation is applied in chemistry. The kinetic theory of gases gives a new, and much deeper, significance to the statement by introducing the conception of the molecule this, however, does not concern us in thermodynamics, and since the molecular weights are purely relative numbers, the deductions made in this hook are equally strict whichever standpoint is adopted.

Robert Hooke, in 1665, was seemingly the next writer to advance the theory of the function of the air in combustion. Hooke concludes that there is a certain substance in the air, which is similar to, if not the same as, a substance contained in saltpeter. This substance has the power to dissolve all combustibles when they are sufficiently heated. Fire may be caused by this solution, which is not merely a phenomenon of motion. The products of this may be aerial, liquid, or solid. In saltpeter this substance is so condensed that there is more of it in a given space than in the same space of air. Combustion in a limited air space ceases when the quantity of this substance in the space is saturated.40 Hooke s promise to explain further this theory was never carried out. Hooke s explanation of combustion is at fault in his supposition of solution instead of combination, and his uncertainty as to what the substance is which in air or in saltpeter supports combustion. 

Mayow was acquainted with the publications of Hooke, Willis, and Boyle, all of whom he cites, the last frequently. His own work may be considered as the final stage of the development of the theory of a nitrous substance in the atmosphere as the cause of combustion of sulphureous (that is, combustible) materials, though he also fails to understand the actual process taking place. Mayow, like Hooke and Boyle, is impressed by the fact that the same substance which enables saltpeter to burn combustibles out of contact with the air, is the substance which maintains combustion in the air. His treatise begins with the...

The foregoing discussion of valence is. of course, a simplified one. From ihe development of the quantum theory and its application to the structure of the atom, there has ensued a quantum theory of valence and of the structure of the molecule, discussed in this hook under Molecule. Topics thal are basically important to modem views of molecular structure include, in addition to those already indicated the Schroedinger wave equation the molecular orbital method (introduced in the article on Molecule) as well as directed valence bonds bond energies, hybrid orbitals, the effect of Van der Waals forces and electron-dcticiem molecules. Some of these subjects are clearly beyond the space available in this book and its scope of treatment. Even more so is their use in interpretation of molecular structure.

Hooke s law relates stress (or strain) at a point to strain (or stress) at the same point and the structure of classical elasticity (see e.g. Love, Sokolnikoff) is built upon this linear relation. There are other relationships possible. One, as outlined above (see e.g. Green and Adkins) involves the large strain tensor Cjj which does not bear a simple relationship to the stress tensor, another involves the newer concepts of micropolar and micromorphic elasticity in which not only the stress but also the couple at a point must be related to the local variations of displacement and rotation. A third, which may prove to be very relevant to polymers, derives from non-local field theories in which not only the strain (or displacement) at a point but also that in the neighbourhood of the point needs to be taken into account. In polymers, where the chain is so much stiffer along its axis than any interchain stiffness (consequent upon the vastly different forces along and between chains) the displacement at any point is quite likely to be influenced by forces on chains some distance away. 

Comprehensive accounts of polar field theories (micropolar and micromorphic) and of non-local field theories are given in the book edited by Eringen4). We return to Hooke s law, oy = C e. ...
