Equilíbrio de um Corpo Rígido
Condições de Equilíbrio
Equilibrium refers to a state where a rigid body is not subjected to any translational or rotational motion. This state is achieved when the force and ...
Reações de Suporte
A coplanar force system refers to a set of forces that all lie in the same plane and are subject to different reactions between the point of contact and ...
Forças Internas e Centro de Gravidade
Internal forces and the center of gravity are fundamental concepts in mechanics, playing a crucial role in understanding the behavior and stability of ...
Conjuntos Alternativos de Equações de Equilíbrio
When analyzing the behavior of structures, engineers often rely on the concept of equilibrium. This refers to the state where all forces and moments ...
Membro de Duas Forças
The equilibrium of a two-force body is a particular case that is often encountered in practical applications. A two-force body is a rigid body that is ...
Membro de Três Forças
A rigid body subjected to three forces acting at three points is known as a three-force member. These forces must have concurrent lines of action, except ...
Equações de Equilíbrio em Três Dimensões
When analyzing structures or systems at rest, it is necessary to ensure they are in equilibrium. This is where the vector and scalar equations of ...
Reações de Apoio em Três Dimensões
Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system ...
Restrições e Determinação Estática
In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. ...
