Non-equilibrium problems such practice mainly refers to a spring of spring in the case of the relative position changes, combined force caused by the acceleration rate of the kinetic energy and other physical changes. Spring will change with the deformation is proportional to the stainless steel spring, and it causes the acceleration speed momentum kinetic energy of an object change is not a simple monotonic relationship, often with a critical value or extreme value. To combine the characteristics of some of the problems to solve simple harmonic motion. 2, integrated problem stretch elastic energy and momentum acting is variable force, seeking elastic and elastic impulse to do when the power butterfly spring, not directly with the impulse and function definitions die springs, generally use the momentum theorem and the theorem of kinetic energy calculation . If the spring is used as an object within the system, the spring will not do within the system object does not affect the system's acting mechanical energy Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stampings business the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world.
