Question

Write the expression for Center of mass of a rigid body, sing this prove that
the external force applied on the rigid body acts on the centre of mass that
is F⃗ex = M × A⃗cm please answer

Answer 1

Explanation:

In the physical science of dynamics, rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces. The assumption that the bodies are rigid (i.e. they do not deform under the action of applied forces) simplifies analysis, by reducing the parameters that describe the configuration of the system to the translation and rotation of reference frames attached to each body.[1][2] This excludes bodies that display fluid, highly elastic, and plastic behavior.
