Description:Use: Used for experiment in physics teaching classes in the middle schools For example: 1st, the helical spring will deform by external force. When there is external force, the deformation will vanish and the spring will restore the original condition. (If external force surpasses elastic definition, even when the external force eliminates, the deformation will not vanish) 2nd, within the elastic definition, the external force is a proportional factor 3rd, spring-loaded thrust meter scale division principle Structure: The 5 kinds of helical springs connected by the steel silk cord are a group, with the respective pulling force of 5N, 3N, 2N, 1N, and 0.5N Superficial nickel plating protection The spring has a ring on the upper side and a red metal piece at the bottom There is no pole inside Specifications: 1st, the lacquered red metal piece is helpful for effectiveness 2nd, the non-linear allowable deviation is not more than 5% 3rd, the rigidity distinction: 5N is 0.025N/mm, 3N is 0.015N/mm, 1N is 0.005N/mm, and 0.5N is 0.0025N/mm
