- Learning Goal: When a rigid body undergoes translation, each particle of the body has the same acceleration ac = a, where ac is the acceleration of the center of mass. Also, the rotational equation of motion reduces to MG= 0. The scalar equations of motion for rectilinear translation, where all particles travel in parallel straight-line paths, become F, = m(ac). F, = m(ac), Σ Mς = 0 where F, and F, are the sum of the forces in the x and y directions, respectively, m is the mass, and MG is the sum of the moments about the center of gravity. The scalar equations of motion for curvilinear translation, where all particles travel in parallel curved paths, become F = m(ac). F = m(ac) Σ ΜΕ = 0 where the subscripts n and t denote the normal and tangential directions of motion, respectively. The moment equation for both types of translation, MG = 0. can be replaced by a summation of moments about an arbitrary point A where the moment of mac must be accounted for with the following equation: Figure < 1 of 2
