## Applied Mechanics and Graphic Statics The condition of equilibrium for any system of forces in a plane is

That resultant couple must be zero
None of these
That polygon of forces must close
Both (A) and (B)

## Applied Mechanics and Graphic Statics Lami's theorem states that

Three coplanar forces acting at a point will be in equilibrium if each force is inversely proportional to the sine of the angle between the other two
If three forces acting on a point can be represented in magnitude and direction by the sides of a triangle, the point will be in the state of equilibrium
Three forces acting at a point are always in equilibrium
Three coplanar forces acting at a point will be in equilibrium, if each force is proportional to the sine of the angle between the other two
