Screw axes and mobility in spatial mechanisms via the linear complex

A screw axis (helical axis or twist axis) is a line that is simultaneously the axis of rotation and the line along which translation of a body occurs. Chasles' theorem shows that each Euclidean displacement in three-dimensional space has a screw axis, and the displacement can be decomposed into a rotation about … See more The proof that a spatial displacement can be decomposed into a rotation around, and translation along, a line in space is attributed to Michel Chasles in 1830. Recently the work of Giulio Mozzi has been identified as … See more Geometric argument Let D : R → R be an orientation-preserving rigid motion of R . The set of these transformations is a subgroup of Euclidean motions known … See more The instantaneous motion of a rigid body may be the combination of rotation about an axis (the screw axis) and a translation along that axis. This screw move is characterized by … See more A screw displacement (also screw operation or rotary translation) is the composition of a rotation by an angle φ about an axis (called the screw axis) with a translation by a distance d along this axis. A positive rotation direction usually means one that … See more The screw axis appears in the dual quaternion formulation of a spatial displacement D = ([A], d).
