机械加工制造类材料力学课程中的弯曲变形内力和内力图教学是课程中的重点与难点,学生学习过程中一般难以掌握。经过多年教学探索和教学实践,总结出一套教学的口诀和比喻,应用在弯曲变形内力和内力图教学中,非常行之有效,对学生的学习具有很大的帮助。 Curvature and Deformation Curvature in Mechanics Course of Mechanics and Manufacturing Materials Curriculum is the key and difficult point in curriculums. It is generally difficult for students to master the learning process. After many years of teaching exploration and teaching practice, summed up a set of teaching formulas and metaphors, applied in the bending deformation of internal and internal force teaching, is very effective, very helpful to students’ learning.
