**Torsional Deformation**. Torque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section.

Hereof, what is the torsional constant?

The

**torsion constant**is a geometrical property of a bar's cross-section which is involved in the relationship between angle of twist and applied torque along the axis of the bar, for a homogeneous linear-elastic bar. The SI unit for**torsion constant**is m^{4}.What is a torsional load?

**Torsion**of circular shafts. Definition of

**Torsion**: Consider a shaft rigidly clamped at one end and twisted at the other end by a torque T = F.d applied in a plane perpendicular to the axis of the bar such a shaft is said to be in

**torsion**. Effects of

**Torsion**: The effects of a

**torsional load**applied to a bar are.

What is the torsional moment?

**Torsion**is the

**twisting**of a beam under the action of a torque (

**twisting moment**). It is systematically applied to screws, nuts, axles, drive shafts etc, and is also generated more randomly under service conditions in car bodies, boat hulls, aircraft fuselages, bridges, springs and many other structures and components.
