The steel shaft has a radius of r=50 mm. Determine the torque (T) applied to the shaft if the two strain gages attached to the shaft surface record the deformations ?? ′ = −80 (10-6) and ?? ′ = 80 (10-6) Take E = 200 GPa, ν = 0.3. (Hint: you can assume that under torsional moment there is no deformation in x and y direction)

A:

Torsion

In mechanical engineering, torque, torsion, and twisting moment are three of the most important concepts which have different meanings. Torque is the consequence of a moment of a force that produces an angular acceleration in a body or induces rotational kinetic energy in a body. For instance, in an automobile, the power transmission shaft is a body that is always under rotation due to the external torque acting on it, this torque is created by the engine.
