The flexibility of the compression bar intensively reflects which factors of the compression bar will affect the critical stress.
A: Length, constraints, section size and shape
B: Material, length and constraints
C: Material, constraints, section size and shape
D: Material, length, section size and shape
A: Length, constraints, section size and shape
B: Material, length and constraints

举一反三
- The compression bar belongs to a slender bar. Whether it is a medium long bar or a short thick bar is determined according to the () of the compression bar. A: length B: Cross section size C: Critical stress D: flexibility
- the factors that affect the ultimate stress are ( ). A: Load B: Material properties C: Section size D: Working conditions
- The factors that affect the working stress of members are () A: Load B: Material properties C: Section size D: Working conditions
- The slender column is under axial compressive load P, the critical load [img=23x22]1803a0faa055141.png[/img] is independent of ( ). A: the material of the column B: the length of the column C: the magnitude of the P D: the shape and dimension of the cross section of the column
- 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
