Consider two identical springs. At the start of an experiment, Spring A is already stretched out 3 cm, while Spring B remains at
the zero position. Both springs are then stretched an additional three centimeters. What conclusion can you draw about the force required to stretch these springs during the experiment
In this interesting exercise we have that spring A is 3 cm longer, due to previous experiments if these experiments did not reach the non-linear elongation point, the cosecant Km of the spring must remain the same, therefore when we lengthen the two springs these the longitudinal are lengthened.
As a consequence of the above according to Hockey law, the prediction of lengthening is the same, therefore the outside is the same in two two systems
