Solution

For a system of concurrent coplanar forces to be in equilibrium, two conditions must be satisfied:

  1. The vector sum of all forces acting on the system must be zero. This is known as the equilibrium condition for forces. It ensures that the system is not accelerating in any direction. This corresponds to the option (b) "Two equilibrium equations of forces are satisfied".

  2. The sum of moments (or torques) about any point must also be zero. This is known as the equilibrium condition for moments. It ensures that the system is not rotating. This corresponds to the option (c) "One equilibrium equation of moments is satisfied".

So, for a system of concurrent coplanar forces to be in equilibrium, both options (b) and (c) must be satisfied.
