问题按照第三强度理论，图示两种应力状态的危险程度是：

选项 A. a)更危险 B. b)更危险 C.两者相同 D.无法判断

答案 B

解析解:a)图中σr3 =σ1 - σ3 = 150 -0 =150MPa b)图中σr3 =σ1 - σ3 = 100 - (-100) = 200MPa 显然b)图σr3更大，更危险。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
