举一反三
- Integrating the Airy stress function due to a concentrated normal force can solve the half-plane problem under the application of a concentrated moment. A: 正确 B: 错误
- The flexure formula is based on the requirement that the ( ) on the cross section is equal to the ( ) produced by the ( ) distribution about the neutral axis.? resultant moment; moment; linear normal stress|resultant moment; moment; nonlinear normal stress|resultant moment; moment; nonlinear shear stress|resultant normal force; force; linear normal stress
- The section where the bending moment diagram has abrupt change is: () A: Section with concentrated load B: Section with zero shear force C: Section with zero load D: Section with concentrated couple
- The cross section of a straight beam remains plane when the beam deforms due to bending. This causes ( ) on one side of the beam and ( ) on the other side. The neutral axis is subjected to ( ) .? normal stress; shear stress; zero stress|tensile stress; compressive stress; zero stress|compressive stress; tensile stress; maximum normal stress|shear stress; normal stress; zero stress
- In the following cases, ( ) belongs to pure bending. A: The external loads act on the longitudinal symmetric plane of the member; B: The members are only bent without torsion and tension deformation; C: The load on the member is only concentrated couples; D: There is no shear force on each cross section of the member, and the bending moment is a constant.
