3.6: Equilibrium Analysis for a Rigid Body

For an rigid body in static equilibrium—that is, a non-deformable body where forces are not concurrent—the sum of both the forces and the moments acting on the body must be equal to zero. The addition of moments (as opposed to particles, where we only looked at the forces) adds another set of possible equilibrium equations, allowing …

11.7: Equilibrium

An object is in static equilibrium, if both the sum of the external forces exerted on the object and the sum of the external torques (about any axis) are zero. If the object is in static equilibrium the center of mass will have no acceleration and the object will have no angular acceleration. In the center of mass frame of reference, the object ...

12.S: Static Equilibrium and Elasticity (Summary)

12.1 Conditions for Static Equilibrium. A body is in equilibrium when it remains either in uniform motion (both translational and rotational) or at rest. When a body in a selected inertial frame of reference neither rotates nor moves in translational motion, we say the body is in static equilibrium in this frame of reference.

5.3: Equations of Equilibrium

In many cases we do not need all six equations. We saw in Chapter 3 that particle equilibrium problems can be solved using the force equilibrium equation alone, because particles have, at most, three degrees of freedom and are not subject to any rotation.

Analyzing a Static Equilibrium Situation. If an object is at rest and is in a state of equilibrium, then we would say that the object is at "static equilibrium." "Static" means stationary or at rest. A common physics lab is to hang an object by two or more strings and to measure the forces that are exerted at angles upon the object to support ...

Static Equilibrium

Static equilibrium points to any body where the sum of the exerting torques and forces on every part of the body happens to be null. Basically, it is a body's equilibrium whose parts are in a state of rest. The essential condition for static equilibrium is that a body is not encountering any form of movement (rotational or translational).

If there is only one external force (or torque) acting on an object, it cannot be in equilibrium. If an object is in equilibrium there must be an even number of forces acting on it. If an odd number of forces act on an object, the object cannot be in equilibrium. A body moving in a circle with a constant speed is in rotational equilibrium.

18.7: Conductors and Electric Fields in Static Equilibrium

Conductors contain free charges that move easily. When excess charge is placed on a conductor or the conductor is put into a static electric field, charges in the conductor quickly respond to reach a steady state called electrostatic equilibrium.. Figure (PageIndex{1}) shows the effect of an electric field on free charges in a conductor.
