Twisting high-strength, readily available polymer fibers, such as those used for fishing lines or sewing thread, to the point where they coil up, allowed construction of highly efficient actuators that could be triggered by a number of stimuli.
Data were collected on children through to the older adult on a series of six strength measurements, all of which were intended to be directly applicable to design: (1) finger push strength, (2) pinch-pull strength, (3) hand grip strength, (4) wrist-twisting strength, (5) opening strength, and (6) push and pull strength.
This paper shows that chiral carbon nanotubes (CNTs) under twisting show highly dependent strength and fracture toughness on (i) the level of axial tension and (ii) the direction of twisting.
The in-plane shear behaviour of URM wallettes strengthened using near surface mounted high strength twisted stainless steel reinforcement (TSNSM) was investigated and in particular, the effectiveness of the reinforcing schemes to restrain the diagonal cracking failure mode was studied.
It is impossible to tell, with Hitchcock, where fear ends and fantasy begins; indeed, the two are twisted together for strength, like the cords of a rope.

The perpendicular layers counter wood's tendency to warp and twist and add strength.
Another 1% is lost in drawing and roving pulling lengths of fiber into longer and longer segments, which are then twisted together for strength.
In addition, the Dll1 blockade protected against OVX-induced reduction of polar moment of inertia, a parameter of bone strength that described the resistance to twisting.
The tensile strength of a rope is actually less that the sum of the tensile strengths of all the fibers that compose it, since some strength is lost by fiber obliquity necessary for twisting [26].
She slowly twists — a feat of strength and balance.
