Springs and Their Types...

 Springs and Their Types  Steel plants are associated with the springs in two ways. Firstly they supply steels of various qualities used in the manufacture of springs and secondly, they use springs of various sizes, shapes and qualities in the equipments used in the steel plant. Definition of spring A spring is an elastic object used to exert a force or a torque and, at the same time, to store mechanical energy. Springs are elastic bodies (generally of metals) that can be twisted, pulled, or stretched by some force. They can return to their original shape when the force is released. In other words it is also termed as a resilient member. The energy expended in deforming the spring is stored in it and can be recovered when the spring returns to its original shape. Generally, the amount of the shape change is directly related to the amount of force exerted. However, if too large a force is applied, then the spring will permanently deform and never return to its original shape. The force can be a linear push or pull, or it can be radial, acting similarly to a rubber band around a roll of drawings. The torque can be used to cause a rotation, for example, to provide a counterbalance force for a machine element pivoting on a hinge. There are several types of springs. Some of them are shown in Fig 1, Fig 1 Types of springs  Objectives of spring  The objectives of a spring when used as a machine member are as follows. Cushioning, absorbing, or controlling of energy due to shock and vibration. Examples are car springs, railway buffers, vibration dampers etc. Control of motion – A spring control the motion by maintaining contact between two elements. In a...
