Mechanical equilib
Mechanical equilibrium
A mechanical equilibrium is a state in which a momentum coordinate of a particle, rigid body, or dynamical system is conserved. Usually this refers to linear momentum. For instance, a linear mechanical equilibrium would be a state in which the linear momentum of the system is conserved as the net force on the object is zero.[1][2] In the specific case that the linear momentum is zero and conserved, the system can be said to be in a static equilibrium[3][4] although for any system in which the linear momentum is conserved, it is possible to shift to a non-inertial reference frame that is stationary with respect to the object.
In a rotational mechanical equilibrium the angular momentum of the object is conserved and the net torque is zero.[2] More generally in conservative systems, equilibrium is established at a point in configuration space where the gradient with respect to the generalized coordinates of the potential energy is zero.
