粗细和长短相同的二圆轴,一为钢轴,另一为铝轴,当受到相同的外力偶作用产生弹性扭转变形时,其横截面上最大剪应力是相同的。
由扭转试验可知，低碳钢试样扭转破坏的断面与试样轴线成45°的倾角，而扭转断裂破坏的原因，是由于断裂面上的剪应力过大而引起的。
An oscilloscope is easily the most useful instrument available for testing circuits because it allows you to see the signals at different points in the circuit.
The best way of investigating an electronic system is to monitor signals at the input and output of each system block, to check that each block is operating as expected and is correctly linked to the next .
