Definition check: Resultant force Statement to evaluate: "A resultant force is a single force which produces the same effect as produced by all the given forces acting on a body." Choose whether the statement is correct or incorrect.

Concept/Approach
The resultant of a system of concurrent forces is the single force that has the same net translational effect (and same net moment about any point if applied at a suitable line of action) as the original system.

Step-by-step
By definition, a single equivalent force can replace a coplanar, concurrent force system without changing the overall mechanical effect.

Common pitfalls
Confusing the resultant force (single force) with a general equivalent system (which could be a force plus a couple for non-concurrent forces).

Final Answer
Correct
