Rotational Equilibrium
Say what??? How does one wrap right-brain around left-brain language?
Isn't rotational equilibrium similar to combustion -- something dynamic? Is not "balance" dynamic???
Rotational equilibrium also applies to sound and color spectrums....
ô What is Rotational Equilibrium?
When an object is in equilibrium, there is no net tendency for it to move or change. When no net force is acting to make an object move in a straight line, the object is said to be in "translational equilibrium." When no net force is acting to make an object turn (torque), the object is considered to be in "rotational equilibrium." An object in equilibrium at rest is said to be in static equilibrium. A state of equilibrium does not mean that no forces act on the body though -- it means that the forces are balanced.
ô Other Terms
Force: A force is a physical influence that produces a change in a physical state. Force equals mass times acceleration. A force can also be defined as a push or a pull.
Torque: A force that tends to produce rotation. Torque equals force times the distance from the force to the center of rotation.
Translational Equilibrium: Translational Equilibrium implies that the sum of all external forces applied to an object is zero.
Equilibrium: An object in equilibrium has no resultant force acting on it. For an object to be in a state of equilibrium it must be both in a state of translational equilibrium and in a state of rotational equilibrium where the sum of all of the torques equals zero.
Static Equilibrium: Static equilibrium exists when the forces on all components of a
system are balanced.
Vectors: A vector is a quantity that has two aspects. It has a size, or magnitude, and a direction. Vectors are usually drawn as arrows. Both force and torque are vector quantities.
Free Body Diagrams: A free body diagram is a tool to calculate the net force on an
object. It is a drawing that shows all the forces acting on an object.
Simultaneous Equations: Simultaneous equations are a set of equations that contain
the same variables. Each solution to the set of equations must simultaneously be a
solution to every equation in the set.
