Why is a pitot type intake divergent in longitudinal cross section?
举一反三
- When a shaft having a circular cross section is subjected to a torque, the cross section remains plane while radial lines rotate. This causes a ( ) within the material that varies ( ) along any ( ) line. A: shear strain; linearly; radial B: normal strain; linearly; radial C: shear strain; nonlinearly; radial D: shear strain; nonlinearly; longitudinal
- For axial compression members, because the normal stress on the cross section is evenly distributed, it is not necessary to consider the reasonable shape of the cross section
- 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
- For a bar under axial tension, the sections with the maximum normal stress and maximum shear stress are A: the cross section and inclined section with inclined angle 45°, respectively. B: both the cross sections. C: the inclined section with inclined angle 45°and cross section, respectively. D: both the inclined sections with inclined angle 45°.
- The torque on the cross section I-I is（ ）N●m。
