1936 Structural Engineer 14 251/2 It is necessary to produce the pretension of the steel and to manufacture concrete of high resistance at a cost sufficiently low to allow one to preserve the greater part of the savings effected on the materials.
1941 Concrete & Constructional Engin. 36 74/1 Shrinkage, elastic deformation, and creep under stress reduce the pre-tension by 10 tons to 20 tons per square inch.
1995 Amer. Jrnl. Vet. Res. 56 694 A method was sought for terminating the ropes so that an appropriate pretension could be introduced into the rope through its interface with the fixator rings.

1937 Rep. Building Res. Board 1936 (Dept. Sci. & Industr. Res.) 99 In connection with some tests on a particular lightweight aggregate, four beams have been tested to determine the effect of pre-tensioning the tension reinforcement.
1973 Sci. Amer. Apr. 114/1 The output of work per cycle can be increased somewhat by pretensioning the fiber before it is immersed in the brine.
