A metallic weight is suspended from a metal spring. If now a current is passed through the spring which will happen?
With the information given, the spring will contract and lift the weight.
What does the inside of a flashlight look like?
There is a metal bar in there and baterieswitha spring in there.
Which is more elastic metal or rubber?
ofcource, metal because it has more regaining property as compared to rubber. according to elasticity -- the body which reform to its original shape or size fast contains maore elasticity.................
What is the tendency for a metal part to return somewhat from to which it has been bent or deformed when the forces causing the change form are removed?
"elasticity" You should note that elastic (as in waist band) is NOT an elastic material. In other words ... the technical and common definitions are quite different.
Why is the spring of the hardness tester never be left under tension?
Any spring that is left under tension will gradually lose its springiness, due to metal fatigue.
Is spring an energy?
Spring the season? No. Spring the metal coiled thing? No, but when compressed or extended it does store potential energy. Spring the water coming up out of the ground? No, although again here energy is involved in order to make it flow.
Whats the difference between the foot band and the foot spring trampolines?
A band trampoline uses elastic bands, while a spring trampoline uses metal springs. The ones that contain bands tend to be safer.
What is plasticity in chemistry?
Plasticity is the characteristic of a metal where it undergoes inelastic strains beyond the elastic limit.Until the elastic limit point, the strain that a metal undergoes is elastic, meaning the metal will regain its original dimensions upon unloading. For example, during a tensile test, a metal pulled in tension to a strain below its elastic limit will return to its original dimensions upon release.However, if a metal is strained beyond the elastic limit into the plastic region, the strain will be inelastic, meaning the metal will be unable to return to its original dimensions upon unloading. Large deformations in ductile materials result in plastic flow.Metals experience periods of both elastic and plastic deformation. On a stress-strain curve, the elastic region is followed by the plastic region. Oftentimes, the elastic limit is approximated as equal to the proportional limit and (for mild steel) the yield stress.
What is the similarity between a rubber band and a metal spring?
Both can store potential energy by being stretched, or by being twisted. They are elastic and if flexed they will exert a force in trying to return to their normal untensioned state.
A metal that returns to its original after being deformed has undergone?
elastic deformation
What is the use of helical springs?
A spring apparatus is often used to figure out the force constant of a spring. It has a ruler, spring (with a circular platform to add masses on) and a needle (place at 0 on the ruler). Because force and distance are directly proportional, as you add masses and see the distance on the ruler you can easily figure out the force constant with the equation Fe = kx , where Fe = FG = mg
In what way metal and wood be made to exert an elastic force?
If I don't understand the question wrongly, I think molten metal might be made to exert an elastic force, though wood - I'm not so sure.
What were the materials to make a ballista?
A ballista was mostly made of wood. The spring system was usually made of ropes, tightly coiled. There were a number of metal parts, such as ratchets and the trigger system, and these could be made of iron or steel.
What metal are bicycle seat spring made from?
what metal is it answer a.s.a.p
Is copper elastic?
Copper is ductile, but not overly elastic. Metals that elastically deform under a load will return to their original shape once the load has been removed, however if it plastically deforms the metal will not return to it's original position once the load has been removed. copper is a pretty ductile metal so it's more likely to plastically deform however there is a small amount of elasticity in copper. more elastic metals would be steels and especially spring steel. However other examples of elasticity outside that of metals is in rubbers and plastics as the elastic property usually results from long, chained molecules called polymers.
What were catapult made from?
The oldest forms of a catapult are known are described about 2,000 years ago. These were based on principles used in the cross bow and therefore required some elastic material to store energy and a structural support to hold the mechanism. The essential elastic element was presumably a wood product just as the elastic element of a bow has been made of wood up until more modern constructions with spring metal and plastic materials.
How does the doorbell able to produce sound?
Electronic doorbells have pre-programmed melodies that they emit over a speaker. Mechanical doorbells are often quit interesting, the have a coiled copper wire that acts as a electric magnet similar to a solenoid. a solid steel rod in the middle of the coil is normally pulled against a elastic spring so that when the coil is energized it will pull the metal part into the coil against the spring the moment that happens a switch is normally pressed by the metal part that breaks the current and de-energize the coil, the now compressed spring will push the steel rod from the coil causing the switch to re-energize the coil...this will allow the steel part to oscillate back and forth in and out of the coil.. the sound is produces by placing a bell shaped metal part in front of the steel part and the steel part is allowed to hit it each time it oscillate and so the sound is produces. Difficult to explain, try finding a picture of a mechanical doorbell.
