IAU Comm.30, IAU XXVIII GA Beijing, August 2012. Torque is the tendency of a force to cause or change rotational motion of a body.. It is to set a standard so a screw or bolt is not under tightened which will result in failure from loosening, or over tightening which can result in breaking or stripping of the screw.. Torsion. Torsional. Deformation of a Circular Shaft. When a torque is applied to a circular shaft. The circles remain as circles. Each longitudinal grid line deforms into a helix that intersects the circles at equal angles. Overview of Why and How. Dan Burbank and Tony Young. AST5022. Introduction. Background. Physics. Sources.
