Mechanics of Materials

The main objective of a basic mechanics course should be to develop in the engineering student the ability to analyze a given problem in a simple and logical manner and to apply to its solution a few fundamental and well-understood principles. This text is designed for the first course in mechanics of materials—or strength of materials—offered to engineering students in the sophomore or junior year. The authors hope that it will help instructors achieve this goal in that particular course in the same way that their other texts may have helped them in statics and dynamics. To assist in this goal, the seventh edition has undergone a complete edit of the language to make the book easier to read.

THEORETICAL MECHANICS

Mechanics may be defined as that science that describe and develop the conditions of equilibrium or of the motion of the material bodies under the action of the forces. Mechanics can be divided in three large parts, function of the studied object: mechanics of the no deformable bodies (mechanics of the rigid bodies), mechanics of the deformable bodies (strength of the materials, elasticity, building analysis) and fluid mechanics.

История Индии

Индия - страна, подарившим человечеству одну из основных мировых религий, высокое искусство и литературу, уникальное зодчество, множество философских учений... Страна, пережившая множество нашествий, однако век за веком сохранявшая самобытность и становившаяся только сильнее. «Жемчужина короны Британской империи» XIX века. Родина Тагора, Ганди и Неру. И наконец, современное, динамично развивающееся государство ставшее на путь модернизации. В своем глубоком, живо написанном исследовании Джон Кей рас­сказывает о самой необычной стране пашей планеты - с древнейших вре­мен и до наших дней.

Matrix Quantum Mechanics and Two-dimensional String Theory in Non-trivial Backgrounds

String theory is the most promising candidate for the theory unifying all interactions including gravity. It has an extremely difficult dynamics. Therefore, it is useful to study some its simplifications. One of them is non-critical string theory which can be defined in low dimensions. A particular interesting case is 2D string theory. On the one hand, it has a very rich structure and, on the other hand, it is solvable. A complete solution of 2D string theory in the simplest linear dilaton background was obtained using its representation as Matrix Quantum Mechanics. This matrix model provides a very powerful technique and reveals the integrability hidden in the usual CFT formulation. This thesis extends the matrix model description of 2D string theory to non-trivial backgrounds. We show how perturbations changing the background are incorporated into Matrix Quantum Mechanics. The perturbations are integrable and governed by Toda Lattice hierarchy. This integrability is used to extract various information about the perturbed system: correlation functions, thermodynamical behaviour, structure of the target space. The results concerning these and some other issues, like non-perturbative effects in non-critical string theory, are presented in the thesis.

Mathematical Tools for Physics

When you address these questions to every problem you ever solve, you do several things. First, you’ll find your own mistakes before someone else does. Second, you acquire an intuition about how the equations ought to behave and how the world that they describe ought to behave. Third, It makes all your later efforts easier because you will then have some clue about why the equations work the way they do. It reifies algebra. Does it take extra time? Of course. It will however be some of the most valuable extra time you can spend. Is it only the students in my classes, or is it a widespread phenomenon that no one is willing to sketch a graph? (“Pulling teeth” is the clich´e that comes to mind.) Maybe you’ve never been taught that there are a few basic methods that work, so look at section 1.8. And keep referring to it. This is one of those basic tools that is far more important than you’ve ever been told. It is astounding how many problems become simpler after you’ve sketched a graph. Also, until you’ve sketched some graphs of functions you really don’t know how they behave.

MATHEMATICAL PRINCIPLES OF NATURAL PHILOSOPHY AND HIS SYSTEM OF THE WORLD

THE ANCIENTS (as we are told by Pappus) esteemed the science of mechan- Sics of greatest importance in the investigation of natural things, and the moderns, rejecting substantial forms and occult qualities, have endeavored to subject the phenomena of nature to the laws of mathematics, I have in this treatise cultivated mathematics as far as it relates to philosophy. The ancients considered mechanics in a twofold respect; as rational, which proceeds accurately by demon- stration, and practical. To practical mechanics all the manual arts belong, from which mechanics took its name. But as artificers do not work with perfect accu- racy, it comes to pass that mechanics is so distinguished from geometry that what is perfectly accurate is called geometrical; what is less so, is called mechanical. However, the errors are not in the art, but in the artificers. He that works with less accuracy is an imperfect mechanic; and if any could work with perfect accu- racy, he would be the most perfect mechanic of all, for the description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geom- etry does not teach us to draw these lines, but requires them to be drawn, for it requires that the learner should first be taught to describe these accurately before he enters upon geometry, then it shows how by these operations problems may be solved. To describe right lines and circles are problems, but not geometrical problems.

Manual on mathematical models in isotope hydrogeology

Methodologies based on the use of naturally occurring isotopes are, at present, an integral part of studies being undertaken for water resources assessment and management. Applications of isotope methods aim at providing an improved understanding of the overall hydrological system as well as estimating physical parameters of the system related to flow dynamics. Quantitative evaluations based on the temporal and/or spatial distribution of different isotopic species in hydrological systems require conceptual mathematical formulations. Different types of model can be employed depending on the nature of the hydrological system under investigation, the amount and type of data available, and the required accuracy of the parameter to be estimated.
