E-STAR - Student
E-Lecture - Equilibrant

We have discussed that the vector sum of two or more forces is the resultant and that the resultant can, in effect, replace the individual vectors. The equilibrant of a set of forces is the force needed to keep the system in equilibrium. It is equal and opposite to the resultant of the set of forces, Figure 9.

The x and y components of the equilibrant will be equal to the negative of the respective values of the resultant. ΣFx = 95.49 N and ΣFy = -70.35 N
