Transmissibility requires that the conditions for equilibrium or motion of a rigid body
will remain unchanged if a force acting at a given point is replaced by a force of the same
magnitude and direction but acting at a dierent point, provided that both forces have the
same line of action. is concept is extensively used in the analysis of structural elements
such as trusses.
Newton’s rst law states that a particle will remain at rest as long as no force acts upon
it or will move at a constant velocity if originally in motion.
Newton’s second law states that if the resultant force acting on a particle is n ...
