HIBBELER 10th EDITIONPROBLEM 2-35

Three forces act on the bracket. Determine the magnitude and direction θ the F1 so that the resultant force is directed along the positive x´ axis and has a magnitude of 1 kN.

HIBBELER 10th EDITIONPROBLEM 2-48

If θ = 60º and F = 20 kN, determine the magnitude of the resultant forcé and its direction measured clockwise from the positive x axis.

HIBBELER 12th EDITIONPROBLEM 2-46

The three concurrent forces acting on the screw

eye produce a resultant force FR = 0. If F2 = 23 F1

and F1 is to be 90ᵒ from F2 as shown, determine the required magnitude of F3 expressed in terms of F1

and the angle θ.
