举一反三
- If the normal stress on the cross section of the axial tensile rod is σ, then the normal stress and shear stress on the 45° degrees section are .

- The main failure modes of inclined section of flexural members can be ordered as ( ) from high to low according to the corresponding shear capacity. A: inclined tension failure > shear-compression failure> inclined compression failure B: shear-compression failure > inclined tension failure > inclined compression failure C: inclined compression failure > shear-compression failure> inclined tension failure D: shear-compression failure> inclined compression failure > inclined tension failure
