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
A: length
B: Cross section size
C: Critical stress
D: flexibility
举一反三
- 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
- There are different kinds of bar, you can see main bar, __________,(酒廊) grand bar, __________, (茶室)service bar, banquet bar, __________(主题酒吧), and gentle bar.
- Under the same material conditions, as the flexibility increases, ( ). A: The critical stress of the long column decreases while that of the medium flexibility bar remains unchanged. B: The critical stress of the intermediate column decreases while that of the large flexibility bar remains unchanged. C: The critical stress of the large and the intermediate column are both decreased. D: The critical stress of the large and the intermediate column are both unchanged.
- The critical pressure of the compression bar is directly proportional to the elastic modulus of the material
- have a drink, bar, let's__________ in the bar.
