ME 3133 Chapter : Lect 16 Rigid Body Kinematics RotationBlanks
Document Summary
New class schedule posted with corrected lecture numbers Assignments: read meriam & kraige: chp 5. 1-5. 4 => rigid body kinematics, practice problems, 14, 25, 27 [28] Planar kinematics of rigid bodies : translation, rotation, example problem(s) Planar kinematics of rigid bodies: rigid body : a collection (system) of particles for which the relative distance (d) between any two particles/points is xed, i. e. remains constant => Deformations (bend, squash, stretch) due to forces occur but are negligible in. ) = constant d = ab ab = ) b a comparison to general motion of the object. Deformations are important in later stress-strain, de ection analysis & design. B d: rigid body kinematics: must account for. Position (r), velocity (v), acceleration (a) of any one point. (radians) relative to fixed reference line. 3: special case for relative motion constraints for two points: rb = ra + rb/a vb = va + vb/a ab = aa + ab/a.
