2、Based on the relationships between loads, shear forces, and bending moments introduced in the video, which one of the choices listed below corresponds to the correct shear force and bending moment diagrams for the following beam?
A:D图 B:C图 C:B图 D:A图 3.
The rate of change of the shear force at any point on the axis of a beam is equal to the intensity of the distributed load at that same point.
A:错 B:对 4.
The change of the bending moment at any point on the axis of a beam is equal to the shear force at that same point.
A:错 B:对 5.
If the shear force at a certain point on the axis of a beam is equal to zero, the bending moment at that same point is also equal to zero.
A:错 B:对 6.
The application of a concentrated force to any point on the axis of a beam leads to an abrupt change in the rate of change of the bending moment at that same point.
A:对 B:错 7.
The shear force at any point on the axis of a beam experiences an abrupt change if a couple is applied to that same point.
A:错 B:对 8.
The bending moment changes abruptly at the point of application of a couple.
A:错 B:对
