The point beyond which a stretched spring does not return…
The point beyond which a stretched spring does not return to its original length is called the
A. breaking point
B. spring constant
C. elastic limit
D. elasticity point.
When a spring is stretched and released, it immediately returns back to its original length, but when it is stretched until its elastic limit is exceeded, the spring then enters the plastic region and loses the ability to return to its original length.
Now for the right answer to the above question:
- Option A is incorrect. breaking point is a point at which the spring gets cut, but before this point, the spring already lost its elasticity.
- Option B is incorrect. spring constant is a varying property of the materials used to make the spring.
- C is correct.
- D is not the correct answer.
You may please note these/this:
- When a spring is stretched until it exceeds its elastic limit, some of its elastic properties will get lost.
