摘要
普通物理“固体的弹性形变”一章教学中,有关螺旋弹簧变形的机理是教学难点,为了帮助学生理解,我们构思设计和制作了演示旋弹簧变形机理的二维模型、三维模型.
In teaching the chapter of 'Solid Elastic Deformation' in General physics, the mechanism of spiral spring deformation is a difficult teaching area. Both 2-D and 3-D models are conceived, designed and fabricate to demonstrate the mechanism of spiral spring deformation in order to help students understand it smoothly. The design-principle and fabrication method of the models. are introduced in this paper.
