The torsion test of a continuous cylindrical specimen is used in this paper to explicitly determine the rheological model of a deformable material. Processing of the results of theStatics - Twisting Moments. Twisting moments, or torques, are forces acting through distances (“lever arms”) so as to pro- mote rotation. The simple example is that of using a wrench to tighten a nut on a bolt as shown in Figure 6: if the bolt, wrench, and force are all perpendicular to one another, the moment is just the force F times the length l of the wrench: \(T = F \cdot l\).

Determine (a) the shear stress, (b) shear strain, and (c) shear modulus, assuming the specimen has not yet yielded.There are two kinds of torsion experiments: torque control and angular speed control. Torque control experiments apply a uniformly increasing torque to the specimen and the amount of strain is measured as an angle through which the specimen has turned. Angular speed control turns the specimen at a specific angular speed while the torque is .One of the most common examples of torsion in engineering design is the power generated by transmission shafts. We can quickly understand how twist generates power just by doing a simple dimensional analysis.Power is measured in the unit of Watts [W], and 1 W = 1 N m s-1.At the outset of this section, we noted that torque was a twisting couple, which means that it has .23.
