Category:Equilibrium (Mechanics)

This category contains results about equilibrium in the context of mechanics.
Definitions specific to this category can be found in Definitions/Equilibrium (Mechanics).

Let $B$ be a particle, a system of particles, or a body.

Let $B$ be such that:

it is subject to neither acceleration nor angular acceleration

the resultant of the external forces acting on $S$ is zero

the sum of all the moments of all the external forces acting on $S$ is also zero.

Then $B$ is said to be in equilibrium.
