Equilibrium of Forces The forces F1, F2, . . . , Fnacting at the same point P are said
Chapter 9, Problem 70(choose chapter or problem)
Equilibrium of Forces The forces F1, F2, . . . , Fnacting at the same point P are said to be in equilibrium if theresultant force is zero, that is, if F1 F2 . . . Fn 0. Find(a) the resultant forces acting at P, and (b) the additional forcerequired (if any) for the forces to be in equilibrium. F1 i j, F2 i j, F3 2 i j
