These axes are called member axes (or local axes) . 这些坐标系叫做杆件坐标系(或局部坐标系)。
The members in fig. 1-45 have a neat fit at the time of assembly . 图1-45中的杆件在安装时已调整好。
Such members are much more flexible in torsion than those with a solid section . 这样的杆件在扭转时比实心截面的杆件柔得多。
Sometimes, however, the ability of bars to deform appreciably in torsion is put to good use . 但是,有时要利用杆件在扭转时具有可观变形的能力。
An internal work product will occur when a bar force, n. is associated with a change of length, e . 当杆件内力N和长度的变化e相结合时就得到内乘积功。
Cracking was initially detected in the east truss at the pin link connection in member l15-l16 . 裂纹首先发现于东侧桁架的L15-L16杆件的枢轴链杆连接处。
Similar comments apply to torsion if the torsional moment and twist per unit length are constant throughout a member . 如果扭矩和单位长度上扭角沿杆件为常量,则上述的结论也可以用于扭矩。
Vertical elements carry sufficient load through cantilever action to produce cantilever deflections equal to arch deflections . 垂直杆件则借悬臂作用产生和拱挠度相等的悬臂挠度,来承担足够的荷载。
Shear stresses and shear strains in prismatic members may be caused by either torsional moments, or by shear forces associated with flexure . 在等截面杆件中,剪应力和剪应变可以由扭矩引起,或者由变曲相关的剪力引起。
