举一反三
- In the following members, which one can be treated as axially loaded member? A: shear wall B: frame beam C: frame column D: member in steel truss
- 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.
- 【单选题】In the following description of a const member, the error is (). (2.0分) A. Const members are specified with the keyword const B. There are two types of const member: const data member and const member function C. The initialization of a const data member occurs when it is defined in the class body D. The value of a const data member cannot be changed
