Both ends of a spring are displaced along its length. Every displacement has an identical magnitude. In which of the following cases does the tension or compression within the spring attain a maximum magnitude?
Options
- AThe right end is shifted leftward and the left end rightward.
- BBoth ends are shifted leftward.
- CBoth ends are shifted rightward.
- DThe right end is shifted rightward and the left end leftward.
Correct answer
D. The right end is shifted rightward and the left end leftward.
Step-by-step solution
Let the magnitude of displacement of each end be x . The tension or compression in a spring is proportional to the change in its length. When the right end is shifted leftward and the left end rightward, the spring is compressed by 2x . The magnitude of deformation is 2x . When both ends are shifted in the same direction (both leftward or both rightward), the net change in the length of the spring is zero. When the right end is shifted rightward and the left end leftward, the spring is elongated by 2x . The magnitu
