‏If you want to describe a product, you can describe its______.‌ A: material B: color C: shape D: size

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.

For the columns with the same length, material, constraint conditions and cross-sectional area, etc., the stability of which kind of shape of cross-section (see the following figures)is best ? . And the stability of which is worst? .http://image.zhihuishu.com/zhs/onlineexam/ueditor/201904/64415e4a30114dd688f87cc28116d571.png
