Torsional Deflection

Torsional deflection, also called torsional deformation or angular deflection, is the twisting of an object around its axis or centerline.  It is a type of deformation that occurs in response to an applied torsional force or moment around the longitudinal axis of the object.

Torsional deflection is commonly observed in objects with a cylindrical or shaft like shape, such as rods, shafts, beams, and other structural members.  When a torque is applied to one end of such an object, it causes one end to rotate relative to the other, resulting in torsional deformation along its length.  Flex connectors should not be put to this type of stress since the objects they are attached to should be secured from rotation.

Torsional deflection is an essential consideration in the design of various engineering systems and components, especially in mechanical systems that involve rotating elements, such as drive shafts, gears, and propellers.  Engineers use mathematical models and formulas based on solid mechanics principles to calculate and predict torsional deflection and ensure that the components can withstand the applied torque without experiencing excessive deformation or failure.
