The condition ∑ fi = 0 is sufficient to assure that a rigid body is in equilibrium.
true
false

The given statement:

The condition ∑ Fi = 0 is sufficient to assure that a rigid body is in equilibrium is a

TRUE statement.

According to the condition for the equilibrium of a rigid body, the vector sum of all the forces acting on the body must be zero.

The first condition of equilibrium for a rigid body is as follows:

                             ∑ Fi = 0

where the expression  ∑ Fi are the sum of all the forces acting on the body.

Hence, the given statement is a TRUE statement.
