Answer
Correct Answer: Correct
Explanation
Concept/ApproachThe 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-stepBy definition, a single equivalent force can replace a coplanar, concurrent force system without changing the overall mechanical effect.
Common pitfallsConfusing the resultant force (single force) with a general equivalent system (which could be a force plus a couple for non-concurrent forces).
Final AnswerCorrect
