Torsional rigidity is the product of shear modulus (G) and polar moment of inertia (J). It shows the resistance offered by a material to angular deformation. In the below figure, the opposite torques (T) applied to the shaft are trying to twist the shaft. and the torsional rigidity is working to oppose the twisting (angular deformation).But, AL = Volume of the object (V), ∴ U = σ2V 2E σ 2 V 2 E. For the variable load or variable cross sectional area with respect to the length of object, the elemental strain energy is given by, dU = P 2 x 2AxE P x 2 2 A x E .dx. The total strain energy can be found as, U = ∫ L 0 P 2 x 2AxE ∫ 0 L P x 2 2 A x E .dx.When a shaft is subjected to a torque or twisting a shearing stress is produced in the shaft. The shear stress varies from zero in the axis to a maximum at the outside surface of the shaft.

Note that the torsional stiffness has dimensions [force] * [length] / [angle], so that its SI units are N*m/rad. For the special case of unconstrained uniaxial tension or compression, Young's modulus can be thought of as a measure of the stiffness of a structure. ApplicationsTorque is the expression of a rotational or twisting force. The engines in vehicles rotate about an axis, thus creating torque. It can be viewed as the strength of a vehicle. Torque is what rockets a sports car from 0-60 kmph in seconds. Torque is also what powers big trucks hauling heavy loads into motion. Note that the SI units of torque is a Newton-metre, which is also a way of expressing a Joule (the unit for energy). However, torque is not energy. So, to avoid confusion, we will use the units N.m, and not J. The distinction arises because energy is a scalar quanitity, whereas torque is a vector. The twisting torque cause torsional shear, which results in the twisting of an object. The angle of twist gives the rotation angle turned by planes of application of twisting torque. The term angle of twist is denoted by the symbol ‘θ’ and it is expressed by the unit of degree or radian.

Typically a …Oct 16, 2023 · In the solid mechanics field, Torsion is defined as the twisting of an object due to a torque applied to it. Torsion can be expressed in either pascals (Pa) or an S.I. unit Newtons per square meter, or in pounds per square inch (psi). In contrast, torque is expressed in Newton-meters (Nm) or foot pound-force (ft.lbf). Unlike in solid mechanics where shear flow is the shear stress force per unit length, in fluid mechanics, shear flow (or shearing flow) refers to adjacent layers of fluid moving parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the ...

The required torsion spring rate is calculated the same way that it is calculated for compression and extension springs but, since this is a radial force and not a linear one, units for spring constant are different. The purpose of this experiment is to measure the torsion constant of a rod by two methods.

Torsional rigidity is that object’s resistance to deformation brought on by torque forces. In a somewhat counter intuitive way, the rigidity can be measured by the amount of torque needed to deform the object. Torsional rigidity is said to be the amount of torque necessary to twist an object by one radian per unit length (of the object).
