举一反三
- In the following cantilever beam, the ( ) of the cross-section C and B is different.[img=617x199]1803a0fa75c83b4.jpg[/img] A: bending moment M B: shear force V C: deflection v D: slope angle [img=9x19]1803a0fa7e46ed5.png[/img]
- The cantilever beam shown here is subjected to two equal and opposite couples，for the section B（ ）.[img=414x136]1803a25c3173b7f.jpg[/img] A: The deflection is zero, the angle of rotation is not zero B: The deflection is not zero, the angle of rotation is zero C: Deflection and angle of rotation are both not zero D: Both deflection and angle of rotation are both zero
- The rotation angle of the cross section at the maximum deflection of the beam must be equal to zero. ( )
- The rotation angle of the cross section at the maximum deflection of the beam must be equal to zero. ( ) A: 正确 B: 错误
- 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
