Spring class of problems is one of the kinds of questions spring common high school physics, and comprehensive, is difficult. Analysis of these kinds of questions on the comprehensive ability to train students in the analysis is very good. 1, at the secondary level, where the springs are not considered related to the quality of the spring, called "Light of the spring." Light Spring is an idealized physical model, with light spring as the carrier, set up complex physical scenario, the concept of test force balance of the object, the application of Newton's laws and energy conversion and conservation. 2, the spring force of the deformation is determined by the force of a magnitude and direction. When the subject appears in the spring, to pay attention to the size and direction of the time to correspond to the elastic deformation at the time of Deformation analysis in the title of the spring should be generally start, first determine the location of the original length of the spring, is now a long position, to identify the variables x and shape change in the position of the object space geometric relationship, corresponding to elastic deformation analysis of size, orientation spring plants, in order to analyze possible changes in the state of motion of the object is calculated .. Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Spring tension springs, compression springs, die springs, torsion springs, automobile springs, construction machinery springs, spring washers, flat washers, cotter pins, spring pin, Dongguan City Xufeng Hardware Factory After years of operating and development company has become the spring, stamping parts and lathe parts design and manufacture of integrated quasi-integrated metal processing enterprises, the company produces various types of tension springs, compression springs, die springs, special springs, torsion springs, spring washers, disc springs and a variety of heterosexual springs and other products, up more than 2000 kinds of specifications models.
