In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. [1][2] Torsion could be defined as strain [3][4] or angular deformation, [5] and is measured by the angle a chosen section is rotated from its equilibrium position. [6] .

Torsion is a type of mechanical deformation experienced by an object when a twisting force is applied to it. In engineering, torsion is commonly observed in shafts and other cylindrical structures that are subjected to torque, resulting in angular displacement and shear stress.

2024年7月19日 · A torsion force is a load that is a applied to a material through torque. The torque that is applied creates a shear stress. If a torsion force is large enough, it can cause a material to undergo a twisting motion during elastic and plastic deformation.

The force that gets developed upon twisting one end of an object while rotating another end in the opposite direction or keeping it in a fixed position is known as torsion force. The response to torsion force depends on the nature of the object.

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. To keep things simple, we're going to focus on structures with a circular cross section, often called rods or shafts.

2025年3月28日 · Normal stresses act to pull parallel planes within the material apart or push them closer together, while shear stresses act to slide planes along one another. Normal stresses promote crack formation and growth, while shear stresses underlie yield and plastic slip.

Torsion. Consider a bar to be rigidly attached at one end and twisted at the other end by a torque or twisting moment T equivalent to F × d, which is applied perpendicular to the axis of the bar, as shown in the figure. Such a bar is said to be in torsion.

The Torsion Formula is a fundamental equation used to analyze the stresses in a structural member subjected to torsional loads. It relates the internal torque applied to the member to the resulting shear stress at any point along the length of the member.

In mechanical engineering, torsion is a critical concept that describes the effect of twisting forces or torques applied to cylindrical or rod-shaped objects. Understanding torsion is essential for designing and analyzing various mechanical systems that involve rotational motion.
