问题 把直径为d=1mm的钢丝绕在直径为2m的卷筒上,钢丝的弹性模量E=200GPa,则钢丝中产生的最大应力为_;若钢丝的容许应力【σ】=200MPa,则所绕钢丝最大直径为_。( )
选项 A. σmax=500MPa; dmax=4mm B.σmax=100MPa; dmax=2mm C.σmax=200MPa; dmax=0.001mm D.σmax=100MPa; dmax=3mm
答案 B
解析

相关内容:直径,钢丝,卷筒,弹性,模量,200GPa,应力,200MPa,所绕

错误啦!

错误信息

  • 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.
