medical Definition of equilibrium. plural equilibriums or equilibria \-rē-ə\ 1 : a state of balance between opposing forces or actions that is either static (as in a body acted on by forces whose resultant is zero) or dynamic (as in a reversible chemical reaction when the velocities in both directions are equal)
Choices A, B and C are vertical forces that do not balance the horizontal component of mooring line tension.
Choice D. Environmental forces such as wind and currents have horizontal components that the mooring line tension opposes. This is the same for ships! Choice D. is the best answer.
