摘要
分别用截面法和固定端约束的方法分析了轴向拉伸与压缩、扭转、弯曲时轴的内力,说明了固定端约束求外力和截面法求内力是统一的,启发学生思考,加深对内力与外力概念的理解。
Separately using section method and fixed constraint analysis of axial tension and compression, torsion, bending axis force, the fixed constraint for the external force and the section method for internal force is unified, inspire students thinking, deepen the understanding of the concept of internal and external forces.
