STATIC EQUILIBRIUM Meaning and
Definition
-
Static equilibrium is a state in which an object or system is at rest and experiences no acceleration or change in its motion. It is characterized by the cancellation of all external forces acting on the object or system, resulting in a balance between the forces. In this state, the object remains stationary or maintains a constant velocity if it was already in motion.
In static equilibrium, the sum of all forces acting on the object is zero. This means that the forces pushing or pulling on the object are equal in magnitude and opposite in direction, resulting in a net force of zero. Additionally, the sum of all torques acting on the object is also zero. Torque refers to the rotational force applied to an object, and in static equilibrium, the clockwise and counterclockwise torques are equal and cancel each other out.
The concept of static equilibrium is crucial in various fields, such as physics, engineering, and architecture. Engineers and architects use static equilibrium principles to design and construct stable structures and buildings that can withstand external forces such as gravity, wind, or seismic activity. Understanding static equilibrium allows them to ensure the safety and stability of these structures.
Overall, static equilibrium describes a state where an object or system is balanced and not experiencing any changes in its motion due to the cancellation of all external forces and torques acting upon it.
Etymology of STATIC EQUILIBRIUM
The word "static" comes from the Greek word "statikos", meaning "causing to stand". "Equilibrium", on the other hand, comes from the Latin word "æquilibrium", which is derived from "æquus" (equal) and "libra" (a balance or scale). Hence, the phrase "static equilibrium" refers to a state of balance or stability where an object or system remains at rest or does not accelerate.
