Question

What is the first condition of equilibrium?

Answer 1

The first condition of equilibrium states that for a body to be in equilibrium, the vector sum of all the forces acting on that body must be zero. Hope that helps you.

Answer 2

So  the question ask to explain and determine the first condition of equilibrium and base on my further research and understanding about the said equilibrium, I would say that the first condition is that for a body to be an equilibrium, the vector sum of all the forces acting on that body must be zero
