Shear distribution of circular cross-section of the internal forces of the internal forces can not assume that the circular section 67. completely parallel: Shear Qo first] shame figure on the cross-section of the cut edge of the p-point internal forces actually tangentially edge of 0 Take this small rectangle abed, its ad Qi Liang surface calipering surface, abed surface lies in the cross section. If the cut surface of the internal forces get illustrated abed r direction can be decomposed into two component ~ and rx2, the former in the radial direction, which is along the tangential direction. rx1 internal force will be with the rest of the shear r] x while since birth. This is along the surfaces ~ Liang Liang Qu 0 adfg role does this shear force can be generated internal forces, so tx1 not exist, cut on the calipering P 'point edge into the internal force will be with the tangential direction. fish hatchery PP chord among the cut point n on the internal forces by symmetrical relationship, we can see its parallel, Q. Therefore, the point of the P and n points. Shears internal forces will intersect the y-axis direction fish hatchery of 1.0. This assumes that the strings on all other points of the internal forces 方向智 shears intersect at the same point O. Scissors and set the points of the string fish hatchery on the internal fish hatchery forces, which are equal to the component into the straight fish hatchery o This assumes two very close indeed Zhen solution (see Love Shi Zhu Q thus assume that Tony 丨 cut internal forces to recommend: Itabashi fry stir and upholstery in Itabashi researchers, engineering products and development of products HE policy and performance targets for sampling fish hatchery and management process can predict the reliability fish hatchery of internal forces balance polygon Coming to cut on a blog recommendation: 0 Level: 2:00 read Popularity: 845 days popularity : 0 Article fish hatchery Writing: 27 Album: 0
