If a spring is compressed, then a
force with magnitude proportional to the decrease in length from the equilibrium length is pushing each end away from the other
.
Do springs have elastic force?
Springs like the spring toy pictured in the Figure below also
have elastic force when they are stretched or compressed
. And like stretchy materials, they return to their original shape when the stretching or compressing force is released. Springs are used in scales to measure weight.
Does a stiffer spring have more elastic spring 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.
Does a compressed spring have more force?
A force is required to compress a spring;
the more compression there is, the more force that is required to compress it further
. Spring constant (k). If a spring is not stretched or compressed, then no work was done by an outside force (Fapplied) therefore it will not have gained or lost any mechanical energy.
Does the spring constant depend on how far the spring is stretched?
More generally, the spring constant of
a spring is inversely proportional to the length of the spring
, assuming we are talking about a spring of a particular material and thickness. … That means that the original mass of gm will only yield a stretch of mm on the shorter spring.
What makes a spring stronger?
If you make the coil diameter larger, your spring index is bigger thus making your spring weaker. … This means that if
you reduce the coil diameter or increase the wire diameter
, your spring will be stronger thus making it more difficult to compress.
Does a compressed spring have more mass?
A compressed spring has
more energy
and hence more mass.
What happens if the spring constant increases?
A stronger spring-with a larger value of k-will move the same mass more quickly for a smaller period. As the spring constant k increases,
the period decreases
. … For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker or in a shorter period.
What indicates the stiffness of a spring?
The letter k
represents the “spring constant,” a number which essentially tells us how “stiff” a spring is. If you have a large value of k, that means more force is required to stretch it a certain length than you would need to stretch a less stiff spring the same length.
What happens to the spring constant when the spring is stretched?
The proportional constant k is called the spring constant. … When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts
a force F = -kx in a direction towards its equilibrium position
.
What happens to the spring constant when the spring is cut in half?
When the spring is cut into two equal halves, the spring constant doubles. We know that force is directly proportional to the length. …
F = kl where k
is the spring constant. Let the new length of the spring be represented as l', therefore l' = l/2.
Does the spring constant have a unit?
The defining character of a spring is that it resists displacement from its rest position with a force which increases linearly: restoring force
What are the 4 types of springs?
Different types of springs:
compression, extension, torsion, & constant force springs
.
What is the strongest spring in the world?
With these characteristics,
Titanium springs
are one of the strongest and most weight-sensitive springs available. Not only are titanium springs exceptionally strong, they are also corrosion resistant. Titanium springs are used in many industries and in many applications, from motor bikes and race cars to aircrafts.
Does cutting springs increase spring rate?
Cutting coils does increase the spring rate
. … The only thing that will change will be the length of the wire used to wind the spring. The longer the wire is the lower the spring rate. As the wire get shorter, such as when cutting the coil, the spring rate increases.
Can we conclude that compressed spring has more mass than the same spring when it is not?
Yes. When you compress a spring you do work on it, adding energy to it. … As you rightly point out, the E=mc2 relation for an object at rest can then lead us to conclude that
the rest mass of a compressed spring exceeds
the rest mass of an uncompressed spring.
