Lami's Theorem

Lami's theorem is related to the system of forces like the magnitude of three coplanar, concurrent and non-colinear forces that keeps a body in static equilibrium. 

Lami's theorem statement :

It is stated that if three coplanar forces acting at a point be in equilibrium, then each force is proportional to the sine of the angle between the other two forces. 

Lami's Theorem

Now we consider the three forces A, B and C acting on a particle or rigid body that all forces making respective angles α, β and γ with each other.

Now we can represent the Lami's theorem in mathematically :

A / sinα = B / sinβ = C / sinγ
