Do springs deform?

Any object will either resist or deform when subjected to outside stress. Springs are specifically designed to deform in order to absorb energy from outside stress, then return to their natural state when they release that energy.

Can a spring last forever?

It depends on the material of the spring. If the spring is not being deformed more than its fatigue limit, then it should last forever- at least on paper. If a spring is stressed more than its fatigue limit, the rate of failure will increase as the amplitude of the stress increases.

Do springs creep over time?

During their life cycle springs are often times exposed to high amounts of mechani- cal stress and increased surrounding temperatures. This causes creep processes in the material, which can impair the function of the springs or even lead to their failure.

How long does it take a spring to wear out?

The industry standard for these springs is a life cycle of about 10,000-15,000 uses or a spring life of about 5 years on average.

Does spring constant change?

And each part will always stretch the same amount in response to the same force. So if the force remains constant but the total length changes, the deformation will decrease proportionately to the length, causing the spring constant to increase inversely to the length.

Do stiffer springs exert more force?

A less stiff object can be stretched or compressed more easily. Comparing two elastic objects, more elastic spring force would act on the stiffer elastic object when they are stretched or compressed by the same length.

Do springs lose force over time?

‘ is the sort of question that often gets asked. The durability of a spring is measured by its ability to not lose force, or shorten under a given force when subjected to spring travel. If a spring is to be durable, the stress in the material must not be greater than the strength of the material permits.

Do springs have memory?

A typical spring is a tightly wound coil or spiral of metal that stretches when you pull it (apply a force) and goes back to its original shape when you let it go again (remove the force). Some alloys have a property called shape-memory, which means they’re naturally springy.

Will keeping magazines loaded weaken spring?

When left loaded to full capacity and not used, most magazines will very slowly lose some amount of spring tension over time. Some springs may stay loaded for decades and still function, and others might wear out after a much shorter period of time.

Does stretching a spring weaken it?

RE: stretching a compression spring They tend to last about 10,000 cycles. They do not fail so to speak but will weaken and cause feeding or ejection problems that call for a replacement.

Is spring constant really constant?

Linear describes the relationship between the force and the displacement. The fact that the spring constant is a constant (it is a property of the spring itself), shows that the relationship is linear. Of course, Hooke’s Law only remains true when the material is elastic.

Does the spring constant depend on the load?

so k=mω2. Since k is the spring constant it doesn’t depend on the mass of the object attached to it, but here m signifies the mass of the object.

What happens when too much force is applied on a spring?

If too much force is applied, one may stretch or compress a spring beyond a certain point that its deformation will occur. On subsequent release of the stress, the spring will return to a permanently deformed shape which will be different from its original shape.

What happens to a spring that is left loaded for years?

A material, when subjected to a load (even below yield strength) for extended periods of time deforms under that load. Here, in this case, the spring left loaded for years could have deformed permanently and may not have launched the projectile, had the temperature in which your toy has been kept all these years were sufficiently high.

What happens when a spring is compressed for too long?

If you keep it compressed for a long time “elastic fatigue” occurs due to which its behaviour becomes less elastic, ie, it does not return to its original configuration, hence deformed (or bent). The repetitive bending and unwinding of a spring causes something called elastic fatigue: that implies loss in elastic nature of the spring.

How do you determine if a spring is durable?

If a spring is to be durable, the stress in the material must not be greater than the strength of the material permits. When a load is applied to a piece of metal, it must deflect first elastically, and if the load is high enough, it will also do this plastically.
