举一反三
- 中国大学MOOC: A beam with rectangular cross section is subjected to pure bending. The normal stress distribution on the cross section should be
- 声束有效截面 effective cross—section of beam
- 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 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
