Consider there are 2 identical springs.

  • One end of the first spring is attached to the wall and the other end is pulled by a force $\vec{F}$. It is depicted as shown in the first figure below.

  • Both ends of the second spring is pulled by a force $\vec{F}$. It is depicted as shown in the second figure below.

Is the elongation for the first case identical to the second case?

Best Answer

Yes, Spring elongation is $\delta= \frac{F}{k}$ regardless of where $F$ comes from.
