摘要: 依据圆柱形弹簧的劲度系数公式和胡克定律,导出了形变前后有重量的弹簧上同一点相对于弹簧固定端的距离关系式,给出了弹簧非均匀形变的数学表述,讨论了弹簧的质量分布和质心位置问题.

关键词: 弹簧, 劲度系数, 胡克定律, 质量分布, 质心, 重力场

Abstract: According to elastic coefficient formula of circular spring and Hooke's law,the formula of the distance of the same particle relative to spring fixation is deduced,a mathematical expression of uneven spring deformation is given,and the mass distribution and the position of the center of mass of a spring are discussed.

Key words: spring, coefficient of stiffness, Hooke's law, mass distribution, center of mass, gravity field
