What happens if a spring is pulled?
If a spring is pulled (or squeezed) from opposite ends with an equal and opposite tension, the amount the length of the spring changes is proportional to the tension. The proportionality constant is a property of the particular spring. A lot springs won’t support a compression (squeeze) at all and will just collapse.
Does a spring exert the same force on both sides?
The two forces have the same magnitude. Since the force the spring exerts on you is equal in magnitude to your weight, you exert a force equal to your weight on the spring, compressing it. The change in length of the spring is proportional to your weight.
When two ends of a spring balance are pulled?
Physical Science The Spring balance shows a reading corresponding to the force at any one end of the Spring balance. At any instant , the force at the two ends will be equal in magnitude. Other wise , the balance will be in a motion , decided by the resultant force.
What happens when a spring is cut into two stiffness?
Hence, when a spring cut into two parts then for every individual part the stiffness becomes double.
Do springs get stiffer over time?
Yup. The springs will become harder over time due to the constant flexing.
What kind of force does a spring apply when it is stretched or compressed?
restoring force
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. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.
Why is spring force negative?
The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium. In Hooke’s law, the negative sign on the spring’s force means that the force exerted by the spring opposes the spring’s displacement.
When two spring balances joined at the free ends are pulled apart both show the same reading explain?
When we pull the balance B, both the balances show the same reading indicating that both the action and reaction forces are equal and opposite. In this case, the pull of either of the two spring balances can be regarded as action and that of the other balance as the reaction.
In what direction is spring balance being pulled by B?
To stretch the spring, the hook must be pulled away from the balance. So balance B is exerting a force on balance A towards the right, and balance A is exerting a force on balance B towards the left.
What will happen to the spring stiffness if the spring is cut into half of its length and the load remains constant?
When a spring is cut in half the material of the halved material stays the same,therefore the stiffness stays the same.
What will be the effect on stiffness of spring if the spring is half then its original length?
When a spring is cut into two halves of equal length, the spring constant of each half doubles. The product of spring constant and length remains constant. Thus K multiplied by length must be same . Thus, the new spring constant will be twice of the original spring constant.
What happens to the force at the ends of a spring?
An object tied to one end of the spring experiences this spring force. The wholeforce. Something tied to the other end experiences by Newton’s 3rd law the same force (in the opposite direction). No need to half it. Seen from each object at the ends of the spring, it would be:
Why can’t you compress a spring?
You can’t really apply a force to the spring unless it pushes back at with the same force (Newton’s 3rd law and all that). So if it just runs away from you, there’s no compression happening. You can compress a spring between your hands in the air if you push in on both ends at once with the same force.
How much force does it take to push a spring back?
If it’s up against a wall, then the wall is going to exert whatever force is necessary to oppose the other force (since it can’t move). If you put 5 N into the spring at the free end, the spring will compress until it’s able to transmit the force to the wall, which will push back with 5 N. It’s kind of like the springs on your car.
What happens to a spring when it breaks?
You get an enormous acceleration for a moment and then something breaks, the spring goes flying away like a bullet, the forces are no longer acting on the spring, and a fraction of a second later we’re solving a different physics problem. Thank you 🙂 . Your explanation is very nice .
