C: weak column
D: medium column
举一反三
- 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.
- Among the following conclusions about the critical stress σcr of the compressive column, the correct one is ( ). A: The σcr value of the long column is independent of the material B: The σcr value of the intermediate column is independent of the flexibility C: The σcr value of the intermediate column is independent of the material D: The σcr value of the small flexibility column is independent of the flexibility
- Among the following conclusions about the critical stress σcr of the compressive column, the correct one is ( ) A: The σcr value of the long column is independent of the material B: The σcr value of the intermediate column is independent of the flexibility C: The σcr value of the intermediate column is independent of the materia D: The σcr value of the small flexibility column is independent of the flexibility
