Normal strain cause a change in of the rectangular element, whereas the shear strain cause a change in its .
举一反三
- 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
- A reduction in an input price will cause a change in quantity supplied but not a change in supply.
- A reduction in an input price will cause a change in quantity supplied but not a change in supply. A: 正确 B: 错误
- It is assumed that, in a concrete pavement normal vectors of the neutral surface are always perpendicular to the neutral surface, and therefore no （） strain in horizontal directions A: normal B: shear C: elastic D: plastic
- to cause a change or have a significant effect on a person or situation
