Suppose a spring with stiffness $k$, is strained by constant forces on each end.
In a frame where the strained spring moves at a constant velocity, what's the total relativistic energy of the moving strained string as $k\to\infty$?

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
The energy is the same no matter what the strain. The stiffness affects the compression of the spring, not the energy. In other words the higher k is the higher the energy density it has in terms of (potential energy)/(strain).
