spring

spring,

in geology, natural flow of water from the ground or from rocks, representing an outlet for the water that has accumulated in permeable rock strata underground. Some of the water that falls as rain soaks into the soil and is drawn downward by gravity to a depth where all openings and pore spaces in the rock or soil have become completely saturated with water. This region is called the zone of saturation, and the water it holds, groundwater. The upper surface of the zone of saturation is called the water table. Above the water table lies the zone of aeration, where the pore spaces in the soil are quite dry and are filled with air. When the upper surface of the groundwater (water table) intersects a sloping land surface, a spring appears. The occurrence of springs is closely related to the geology of an area. If an impervious layer of rock, such as a clay deposit, underlies a layer of saturated soil or rock, then a line of springs will tend to appear on a slope where the clay layer outcrops. Igneous rocks are also impervious to water, yet they are often extensively fractured, and springs commonly appear where these fractures come to the surface. Fractures in limestone are often enlarged by the dissolving action of groundwater, forming small underground channels and caves. Where these channels outcrop, springs are likely to be found. Springs are common along major faultsfault,
in geology, fracture in the earth's crust in which the rock on one side of the fracture has measurable movement in relation to the rock on the other side. Faults on other planets and satellites of the solar system also have been recognized.
..... Click the link for more information. because groundwater reaches the surface along the fault plane. Lines of springs help locate the position of faults such as the San Andreas of California. Springs can be a valuable water resource, and improvement in flow can often be accomplished simply by driving a pipe into the ground at the point where water seeps from the ground. Sometimes it is advisable to divert the spring water into a cistern or other storage reservoir from which the water can be pumped at will. When the water, because of the geological structure of the strata, issues under pressure, the spring is called artesian (see artesian wellartesian well,
deep drilled well through which water is forced upward under pressure. The water in an artesian well flows from an aquifer, which is a layer of very porous rock or sediment, usually sandstone, capable of holding and transmitting large quantities of water.

[Icel.], hot spring from which water and steam are ejected periodically to heights ranging from a few to several hundred feet. Notable geysers are found in Iceland, New Zealand, and W United States, which are areas of recent volcanic activity.
..... Click the link for more information. . Hot springs occur when the water issues from great depths or is heated by near-surface hot volcanic rock, as in Yellowstone National Park, Iceland, and New Zealand. Mineral springs are those with a high mineral content, usually silica or lime, dissolved from the rocks through which the water has passed (see mineral watermineral water,
spring water containing various mineral salts, especially the carbonates, chlorides, phosphates, silicates, sulfides, and sulfates of calcium, iron, lithium, magnesium, potassium, sodium, and other metals. Various gases may also be present, e.g.
..... Click the link for more information. ). Many ancient city-states, such as Troy, had their sites determined by springs. Pioneer farmhouses often were located in the same way.

spring,

in mechanics, any of several elastic devices used variously to store and to furnish energy, to absorb shock, to sustain the pressure between contacting surfaces, and to resist tensional or compressional stress. Springs are made of an elastic material, e.g., specially formulated steel alloys or certain types of rubber or plastic. A torsion spring that stores energy, e.g., for operating a watch, is a metal strip wound spirally around a fixed center. For reducing concussion in some heavy trucks and railroad cars, helical, or coil, springs are used. Coil springs are commonly used for the same purpose in automobiles, as are leaf springs that consist of flat bars clamped together. These have been replaced in some vehicles by torsion bars that absorb stresses by twisting. The helical-coil compression spring provides the force to keep the operating surfaces together in the friction clutch (see transmissiontransmission,
in automobiles, system of parts connecting the engine to the wheels. Suitable torque, or turning force, is generated by the engine only within a narrow range of engine speeds, i.e., rates at which the crankshaft is turning.
..... Click the link for more information. ). The extension spring is employed for the spring balance; the distance through which it is extended depends on the weight suspended from it. The disk spring, which consists of a laminated series of convex disks, is widely employed for heavy loads.

Spring

an elastic element used to absorb shocks and vibration, supply motive power, and store mechanical energy.

Springs are distinguished on the basis of the following: (1) the type of load accepted, for example, tension, compression, torsion, or deflection springs, (2) the nature of the action of the load, for example, static action, limited short action, or repeated pulsating action, (3) the type of design, for example, coil or helical (primarily cylindrical and conical), spiral, flat, disk, and ring designs, and (4) the characteristics of the spring, for example, whether it has a uniform or variable rigidity.

Springs are manufactured on spring-coiling machines or by hand on mandrels and are usually made of spring steel or bronze for use in corrosive mediums.

Spring

a type of shock-absorbing, elastic device, used in vehicle suspensions, for instance, in motor vehicles, railroad cars, and locomotives. Springs transmit the load from the body to the bogies, wheels, crawler treads, skis, or runners and soften bumps and jolts when traversing irregularities in the road. There are metal, hydraulic, and pneumatic springs.

Figure 1. Leaf spring for the rear axle of a motor vehicle: (1) leaf, (2) clamp, (3) hanger

Metal springs are the most common type; they are classified as leaf springs, torsion bars, and coil springs. A leaf spring (Figure 1) consists of a stack of tempered steel leaves of varying length connected by clamps. The clamps rest on the running gear chassis components of the vehicle and prevent relative lateral displacement of the leaves. The free ends of the leaves are hinged to the body through shackles, lugs, or special hangers. A leaf spring works as a flexible beam upon bending. The leaves are given a bent form to reduce the working stresses. A coil spring has one or several coils (helical, spiral, parabolic, or disk-shaped) arranged one within the other or one over another. Coil springs are often used in conjunction with leaf springs, for example, on railroad cars (Figure 2). Coil springs are the most sensitive to changes in load; leaf springs are best for damping vibrations, thus providing a smoother ride.

Figure 2. Combination suspension for railroad rolling stock

In hydraulic springs, a fluid flows from one chamber of a cylinder to another through grooved passages. In pneumatic springs, the elastic properties of air or a gas may be used.

What does it mean when you dream about spring?

Spring symbolizes new tasks and creative endeavors.

spring

[spriŋ] (astronomy) The period extending from the vernal equinox to the summer solstice; comprises the transition period from winter to summer. (engineering) To enlarge the bottom of a drill hole by small charges of a high explosive in order to make room for the full charge; to chamber a drill hole. (hydrology) A general name for any discharge of deep-seated, hot or cold, pure or mineralized water. (mechanical engineering) An elastic, stressed, stored-energy machine element that, when released, will recover its basic form or position. Also known as mechanical spring.

Spring (machines)

A machine element for storing energy as a function of displacement. Force applied to a spring member causes it to deflect through a certain displacement, thus absorbing energy.

A spring may have any shape and may be made from any elastic material. Even fluids can behave as compression springs and do so in fluid pressure systems. Most mechanical springs take on specific and familiar shapes such as helix, flat, or leaf springs. All mechanical elements behave to some extent as springs because of the elastic properties of engineering materials.

The most frequent use of springs is to supply motive power in a mechanism. Common examples are clock and watch springs, toy motors, and valve springs in auto engines. A special case of the spring as a source of motive power is its use for returning displaced mechanisms to their original positions, as in the door-closing device, the spring on the cam follower for an open cam, and the spring as a counterbalance. Frequently a spring in the form of a block of very elastic material such as rubber absorbs shock in a mechanism. Springs also serve an important function in vibration control.

Springs may be classified into six major types according to their shape. These are flat or leaf, helical, spiral, torsion bar, disk, and constant force springs. A leaf spring is a beam of cantilever design with a deliberately large deflection under a load. The helical spring consists essentially of a bar or wire or uniform cross section wound into a helix. In a spiral spring, the spring bar or wire is wound in an Archimedes spiral in a plane. A spiral spring is unique in that it may be deflected in one of two ways or a combination of both of them (see illustration). A torsion bar spring consists essentially of a shaft or bar of uniform section. The disk spring consists essentially of a disk or washer supported at the outer periphery by one force and an opposing force on the center or hub of the disk. A constant force spring is used when a constant force must be applied regardless of displacement.
