The area of solid mechanics involves the disciplines related to the behavior of deformable solids in both the static and dynamic cases. This is done by studying the mechanics of solids and understanding the two main variables that must be known, which are the mechanics of rigid solids and the mechanics of deformable solids. Mechanics of the rigid solid. The mechanics of the rigid solid relies on the mechanics of particle systems, and in this sense, it does not provide new physical laws. However, the rigid solid model has important theoretical and practical consequences. To study the behavior of solids, we will separate it into three parts. Kinematics. The kinematics of the rigid solid is an application to the movement of a rigid three-dimensional object in space. The more general movement of the rigid solid can be considered as the superposition of two basic types of movement, translation and rotation. For example, the planet Earth is a rigid object which meets the basic conditions of kinematics, moving through space while rotating, thus meeting both variables at the same time. Static. Static is the part of mechanics that studies bodies in a state of equilibrium subjected to the action of forces. Dynamics of a rigid solid. A rigid solid is a system of particles in which the relative distances between them remain constant. The center of mass of the solid moves as a mass point equivalent to the total mass of the system thrown into the air. Therefore, it describes a parabolic movement. Mechanics and deformable solids. The study of mechanics and deformable solids looks at the behavior of deformable solid bodies in different types of situations, such as the application of loads or thermal effects. Types of deformable solids. Deformable solids differ from each other in their constitutive equation. Depending on the constitutive equation that relates the relevant mechanical and thermodynamic magnitudes of the solid, the following classifications are available for the behavior of deformable solids. Elastic behavior. The elastic behavior of a solid occurs when a solid is deformed by acquiring greater potential elastic energy and increases its internal energy without irreversible thermodynamic transformations. The most important characteristic of elastic behavior is that it is reversible. If the force that causes the deformation is suppressed, the solid returns to the initial state prior to the application of the loads, that is its original state. Viscous behavior. The viscous behavior of a solid occurs when the viscosity of the deformation enters the constitutive equation. Typically, in order to deform with a higher deformation rate, it is necessary to apply more tension to obtain the same deformation with a lower deformation rate, but applied longer.

Course Description

In this course on General Engineering and Scientific Processes, you will learn about basic mechanics, fluid mechanics, and thermodynamics. You will be introduced to rigid solids and deformable solids. You will also learn about static and dynamic fluid mechanics, as well as thermodynamics.

To study the behavior of solids, we will separate it into three parts: kinematics, static, and dynamics of rigid solids. The study of mechanics of deformable solids looks at the behavior of deformable solid bodies in different types of situations such as the application of loads, or thermal effects. Deformable solids are divided into two classifications, elastic and viscous behavior.

You will learn about fluid mechanics, both static and dynamic. Static fluids are fluids that are at rest and appear to have no movement, whereas dynamic fluids are those that are in motion. We will discuss the four characteristics of static fluids as well as the two main forms of dynamic fluids. Lastly, you will examine thermodynamics, which is the part of physics that studies heat transfers, energy conversion, and the ability of systems to produce work. While studying thermodynamics, we will discuss the four laws of thermodynamics.
