Dear student,
In case of particle mechanics, the notion of rotation does not apply, and the particlesare said to be in static equilibrium and the sum of the external forces acting on the particle of interest, in all directions, equals zero.

Whereas in case of rigidbody mechanics, the notion of rotation applies i.e. the distances between pointsremains invariant, and the rigid bodies are said to be in staticequilibriumwhen
(a)the sum of the external forces in all directions equals zero, and
(b) the sum of the external moments in all directions equals zero.
Regards
Sumit
