On Determining Parameters of the Twist-Axis for the Finite Displacement of a Body

Conference paper

Abstract

It is well known that a general displacement of a rigid body may be regarded as a finite twisting motion upon an axis in space. Such a twist axis may be treated as a screw when a measure of pitch appropriate to finite twists is used. The author has recently shown that when the displacement of a specialised, axi-symmetric, body is considered, each of the infinity of finite twist screws which are then available for the displacement is a linear combination of just two of their number.

This result is here exploited to derive parameters of the finite twist axis for displacement of a generally shaped body.
