Equilibrium of a Rigid Body
شروط التوازن
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 ...
ردود الفعل الداعمة
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 ...
القوى الداخلية ومركز الثقل
Internal forces and the center of gravity are fundamental concepts in mechanics, playing a crucial role in understanding the behavior and stability of ...
مجموعات بديلة من معادلات التوازن
When analyzing the behavior of structures, engineers often rely on the concept of equilibrium. This refers to the state where all forces and moments ...
عضوان في القوة
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 ...
ثلاثة أعضاء في القوة
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 ...
معادلات التوازن في ثلاثة أبعاد
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 ...
دعم ردود الفعل في ثلاثة أبعاد
Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system ...
القيود والتحديد الإحصائي
In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. ...
