What does equilibrating mean?
Equilibrating is the present participle and gerund of the verb equilibrate, meaning to bring something into a state of balance or equilibrium, or to keep it there. It is most at home in technical registers: chemists speak of a reaction equilibrating as forward and reverse processes come to offset one another, physicists describe pressures or temperatures equilibrating between two bodies, and economists use it for markets or policies that balance competing forces. The word derives from Latin aequus ('even') combined with libra ('scales' or 'balance'), so its core image is that of a set of scales settling level. Though precise and useful where ordinary words like 'balancing' feel too loose, it remains largely absent from casual conversation; most speakers reach for 'balance', 'stabilize', or 'even out' instead. Its noun counterpart, equilibration, names the process itself.

Etymology of equilibrating
Equilibrating comes from the verb equilibrate, formed from Latin aequilibrium (aequus, 'even' or 'equal', plus libra, 'scales' or 'balance'), which English borrowed via the older noun 'equilibrium'. The verb emerged later, with adjectival uses appearing around the early 18th century and verbal use becoming established thereafter. It shares its root with other aequus-derived words such as 'equator', 'equable', and 'adequate'.
