Equilibrium of a Rigid Body

Conditions of Equilibrium
Conditions of Equilibrium
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 ...
Support Reactions
Support Reactions
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 ...
Internal Forces and Center of Gravity
Internal Forces and Center of Gravity
Internal forces and the center of gravity are fundamental concepts in mechanics, playing a crucial role in understanding the behavior and stability of ...
Alternative Sets of Equilibrium Equations
Alternative Sets of Equilibrium Equations
When analyzing the behavior of structures, engineers often rely on the concept of equilibrium. This refers to the state where all forces and moments ...
Two Force Member
Two Force Member
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 ...
Three Force Member
Three Force Member
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 ...
Equations of Equilibrium in Three Dimensions
Equations of Equilibrium in Three Dimensions
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 ...
Support Reactions in Three Dimensions
Support Reactions in Three Dimensions
Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system ...
Constraints and Statical Determinacy
Constraints and Statical Determinacy
In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. ...
