The phrase "angle of twist" is correct and usable in written English.
It is typically used in engineering and physics contexts to describe the amount of rotation or twisting that occurs in a material or structure when subjected to a torque.
Example: "The angle of twist in the shaft was measured to ensure it met the design specifications."
Alternatives: "twist angle" or "torsional angle".
The ultimate strength and modulus of the twisted yarns increase with increasing angle of twist to a maximum of 162±8.5 MPa and 5.9±0.3 GPa, respectively, at an angle of 9.3°.
In addition, the stalling angle of twisted blade is shifted by 25° with the increase in angle of twist from α = 0° to 12.5°, and the stalling angle shifts further with the increase of twist angle.
Based on the parametric studies, it is found that the instability behavior of twisted cross-ply cantilever panels is greatly influenced by the geometry, material, angle of twist and lamination parameters.
Early sails had a constant angle of twist; variable twist sails resembling a modern airplane propeller were developed much later.
In the first set of experiments, specimens were subjected to an initial angle of twist in the elastic range followed by axial load, maintaining initial angle of twist.
The gaps close monotonically as the angle of twist increases for natural frequencies and buckling compressions.
The sensitivity of the detector as a function of the angle of twisting of the cantilever was calculated by accounting for the specific geometry of the laser optical system and detector.
We considered various initial angles of twist to depict linear/nonlinear characteristics of torsional oscillators.
We show that the applied torques and angles of twist at the buckling and failure stages strongly depend on the level of tensile loading and on the twist direction.
If symmetry of the bridge about the deck's centerline is suddenly lost, such as by the failure of one or more cables or hangers (suspenders), torsional motion of the deck may grow and angles of twist may become large.
The improvement is found to be not very sensitive to the slight changes in the width and twist angle of the twisted tape.
