一、求剪力、弯矩求某横截面上的剪力、弯矩如同求解悬臂梁的支座反力。求解时,该截面为固定端,所取的研究对象为悬臂梁。
First, find the shear force, bending moment for a certain cross-section of the shear force, bending moment as to solve the cantilever beam bearing reaction force. When solving, the section is a fixed end, and the object of study is a cantilever beam.
