Mechanical property measurement hand test

On the other hand, it is at the limit of near-perfect transferability of group properties as exhibited by the alkanes that one can detrmine whether or not a proposed theory meets the requirements of experiment, for at this limit one may experimentally determine to high precision the properties of atoms in molecules via their additive contributions. By demonstrating that the atoms defined by quantum mechanics account for and recover the experimentally measured properties of atoms in molecules, one establishes that the atoms of theory are the atoms of chemistry. There is no test of theory other than the demonstration that it predicts what can be measured. 

In the first volume, we focused on adhesion with or without the use of an adhesive, and we were chiefly concerned with mechanisms of bond formation. In this volume, we are interested in both bond-forming and bond-breaking processes. Since polymeric adhesives will be at the center of our discussions, we need to know their physical properties as well as their related measurements. After we apply an adhesive to an adherend, we must understand how to determine bond strengths. With data on hand, we should also learn how to analyze the test results and make certain predictions about the durability of adhesive bonds. Though the entire process sounds rather difficult, we hope that readers will find this volume of benefit.
