ME 3133 Chapter : Lect 01 Intro Rectilinear Kinematics 2PP
Document Summary
Success in dynamics: dynamics is about coordinate systems: Much of dynamics is essentially looking at relative motion of coordinate systems => some fixed/inertial, some moving. Begin thinking in terms of vectors: review vector operations & properties (appedix c in text, think in terms of vector properties (has a physical significance) Can simplify the strategy for solving many problems. Answers can be expressed in terms of any coordinate system: prudent choice of coordinate systems can simplify problem formulation & solution strategies (both kinematics & kinetics, dynamics is word problems: A = (x,y: m - mass, (x,y) - position in 2d, 2 degrees of freedom (dof) in the plane, m & i - both mass & rotational inertia, (x,y, ) - position & orientation in 2d (3dof) Particle vs rigid body: choice often dictated by: Scale of which problem is viewed & Getting started => particle kinematics: rectilinear motion.
