B: Only axial force is considered
C: Bending moment and shear force are considered
D: Bending moment and axial force are considered
A: Only bending moment is considered
B: Only axial force is considered
C: Bending moment and shear force are considered
D: Bending moment and axial force are considered
举一反三
- The internal forces in a thin plate under bending deformation include: A: bending moment B: twisting moment C: shear force D: axial force
- The distribution bending moment in the moment distribution method is equal to: A: Fixed end bending moment B: Distal bending moment C: The inverse of the unbalanced moment is multiplied by the distribution coefficient D: Multiplying the bending moment of the fixed end by the distribution coefficient
- In the following cantilever beam, the ( ) of the cross-section C and B is different.[img=540x190]1803a365910cafa.png[/img] A: Slope angle θ； B: Shear force Fs; C: Deflection y; D: Bending moment M.
- 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
- 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.
