Further strain

The synonym of "strain" is ______.

Normal strain cause a change in of the rectangular element, whereas the shear strain cause a change in its .

Which of the following statements is correct ? (1) There are two types of strains, linear strain(ε) and shearstrain(γ). (2) Strain is dimensionless. (3) If all parts of the object are not deformed, the strain at all points in the body is zero. (4) If the strain of each point is zero, the object has no displacement.

名词解释：strain in compression

The statement that the average strain of the section conforms to the plane section assumption means that the strain of a section in the cracked section conforms to the plane section assumption.

When a shaft having a circular cross section is subjected to a torque, the cross section remains plane while radial lines rotate. This causes a ( ) within the material that varies ( ) along any ( ) line. A: shear strain; linearly; radial B: normal strain; linearly; radial C: shear strain; nonlinearly; radial D: shear strain; nonlinearly; longitudinal

The representative strain that can represent the typical characteristics of a strain is called ( ). A: Model species B: Typical species C: Representative species D: Reference species

智慧职教: Further strain __________ further swelling.
