- There is no neutral layer (one layer without deformation) for a bar under the combination of tension and bending. A: 正确 B: 错误
- 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.
- A typical neutral network includes layer, hidden layers and output layer.
- The internal forces in a thin plate under bending deformation include: A: bending moment B: twisting moment C: shear force D: axial force
