Dinámica y estática



MECHANICS I STATICS+++
The content of the Mechanics I textbook includes methods for determining stresses and strains in uniaxial members, column buckling loads, and a discussion of material properties and material behavior.? Because we have included three topics not normally found in traditional Statics books, we have added the three plus signs to the subtitle Statics +++.? ? We introduced the concept of stresses in uniaxial members, because an analysis of the forces in some structural element is incomplete.? Determining the force is not sufficient to establish the safety of the structural member or to design its cross section.? However, it is easy to introduce stresses in uniaxial members s = P/A, and we have taken this important step toward a more complete analysis.? Next, we added a chapter on materials and material properties introducing yield and ultimate tensile strength.? Determining the stress and comparing this value with the strength of an engineering material enables the student to establish the safety factor or the margin of safety of the structural element.? We have found that extending the analysis to incorporate s

ESTATICA (GAMIO, LUIS)
Material indispensable dirigido a estudiantes y profesionales de las carreras de ingeniería, y fundamental para el aprendizaje de la ingeniería estructural. Tiene el propósito de ofrecer al usuario información inédita referente a centros de gravedad, momentos de inercia, productos de inercia, entre otros temas más. También explica cómo se generan las fuerzas internas en barras, vigas, cables, pórticos y arcos. El libro ofrece una presentación clara y concisa de contenido teórico y, además, está reforzado con ejercicios prácticos, con diferentes grados de dificultad. Todo ello permite que temas como fuerzas concurrentes, pares de fuerza, fuerzas coplanares, fuerzas paralelas, torsor, fuerzas distribuidas sobre líneas, fuerzas distribuidas sobre superficies planas, entre otros, sean de gran utilidad para el entendimiento de la estática.

DYNAMICAL SYSTEMS (TENREIRO MACHADO, JOS‚ A.)
Complex systems are pervasive in many areas of science integrated in our daily lives. Examples include financial markets, highway transportation networks, telecommunication networks, world and country economies, social networks, immunological systems, living organisms, computational systems and electrical and mechanical structures. Complex systems are often composed of a large number of interconnected and interacting entities, exhibiting much richer global scale dynamics than the properties and behavior of individual entities. Complex systems are studied in many areas of natural sciences, social sciences, engineering and mathematical sciences. This special issue therefore intends to contribute towards the dissemination of the multifaceted concepts in accepted use by the scientific community.
