旋转斜杆内的张力

Inside Tension of a Rotatory Ablique Rod

对于处于平衡状态的直杆,只要已知杆段所受的外力,由平衡条件和变形条件一般能比较容易地求得杆中各截面上的内力.而本文讨论的是旋转着的细斜杆在两种情况下杆内张力的变化规律.

For a straight rod of be in equilibrium ,so long as known outside force of act on a section of the rod, apply condition of equilibrium and become deformed, internal force of every cross section in the rod is easy to compute obtain .In the paper , inside tension of a rotatory oblique rod is discuss ,distinguish two different condition.
