Yes, the equilibrium is being achieved w.r.t the ground. Like the motion, w.r.t ground need be zero. That is the relative velocity of the object or the body must be zero w.r.t the ground. This means motion is in equilibrium.

Equilibrium of a body tied to three or more ropes
When a body is tied to three or more ropes and allowed to achieve its equilibrium, the equilibrium achieved is with respect to the ground. Let's understand why.
1. Understanding equilibrium
Equilibrium refers to a state where the net force and net torque acting on a body is zero. In simpler terms, it means that the body is not moving and not rotating.
2. Forces acting on the body
When a body is tied to three or more ropes, it experiences forces from each rope. These forces can be vertical, horizontal, or inclined depending on the arrangement of the ropes. The ropes apply tension forces on the body to keep it in place.
3. Equilibrium conditions
To achieve equilibrium, the body must satisfy two conditions:
- The vector sum of all the forces acting on the body should be zero.
- The vector sum of all the torques acting on the body should be zero.
4. The role of the ground
In the given scenario, the body is tied to three or more ropes, which means it is suspended above the ground. The ground acts as a support and provides a reaction force to counterbalance the forces applied by the ropes.
5. The role of the ropes
The ropes only provide tension forces to hold the body in place. They do not determine the equilibrium position or the direction in which the body will settle.
6. The importance of the ground
The ground is the fixed reference point for the body to achieve equilibrium. It provides the necessary reaction force to balance the forces applied by the ropes. Without the ground, there would be no reference point for the body to achieve equilibrium.
Conclusion
In summary, when a body is tied to three or more ropes and allowed to achieve equilibrium, the equilibrium achieved is with respect to the ground. The ground acts as a fixed reference point and provides the necessary reaction force to balance the tension forces applied by the ropes. The ropes themselves do not determine the equilibrium position or the direction in which the body settles.
