The internal forces in a thin plate under bending deformation include:
A: bending moment
B: twisting moment
C: shear force
D: axial force
A: bending moment
B: twisting moment
C: shear force
D: axial force
举一反三
- When calculating the displacement of composite structure: 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
- An axial compressive force F＝Fcr is acting on an ideal column in linear equilibrium. And then the column produces the bending deformation due to a small lateral disturbing force. If the disturbing force is removed at this time, ( ) . A: The bending deformation will disappear and return to a straight line B: The bending deformation is reduced and the straight line shape can not be restored C: The bending state is not changed D: The bending deformation continues to increase
- 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
- 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
