bar cross section的意思|示意

Rack and pinion: Mechanical device consisting of a Bar of rectangular cross section (the rack), having teeth on one side that mesh with teeth on a small gear (the pinion).

齿条和小齿轮：一种机械装置，由一条矩形截面的杆(齿条)和一个与齿条上的齿相啮合的小齿轮组成。

The bar steels adopt I steels, Angle steels or channel steels, or adopt steel plates which are welded into a cross shaped section.

型钢选用工字钢、角钢或槽钢，或者采用钢板焊接为“十”字型截面。

In this paper, the torsion crack problem for a bar with cross section containing cusp points is discussed.

在本文中讨论了带裂纹杆的扭转问题，并设扦的截面周边具有回归点。

Applying classical wave theory, a concept of equivalent elastic modulus on propagation speed modification of guided wave through "variable cross-section" of metal bar embeded layer was put forward.

运用波动的经典理论，提出了导波在金属杆嵌入层“变截面”传播时波速改变的“等效弹性模量”的概念。

Therefore, the strength check of multi-internal force from the cross-section of bar can be resolved by means of mechanical method.

为此，利用材料力学方法可以解决杆件横截面上存在多个内力的强度计算问题。

But when the bar of the structure is subjected to a lot of lateral loads, or when it is with variable cross-section, the resolving process could become quite tedious.

而当结构中的杆件受到较多的横向载荷作用时，或者结构中的杆件为变截面时，这种方法解题过程变得非常冗长。
