Springs in Parallel

    When springs in parallel are replaced by a new spring of a new effective spring constant, for the proof of this, i.e

    Why do we assume the extension in the springs to be equal?

    If you imagine two adjacent blocks being held together by two springs, if you stretch the blocks apart, the springs stretch equally.

    For the sake of the derivation, you assume that the little block is pulled evenly so that both springs are extended the same amount.
