In statics, Lami’s theorem is an equation that relates the magnitudes of three coplanar, concurrent and non-collinear forces, that keeps a body in static equilibrium.
Lami’s theorem states that if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two forces.
Consider three forces A, B, C acting on a particle or rigid body making angles α, β and γ with each other.
According to Lami’s theorem, the particle shall be in equilibrium if
The angle between the force vectors is taken when all the three vectors are emerging from the particle.

This site helped me in between my viva i m thankful to the creator
It’s usefull in revison
thanks for the helpful information
thanks
This really helped me i couldnt find it in my normal textbook, thanks a lot
This is a helpful site by which my viva exam is best.all my thanks
thanks to representer
Best helpful in my lab
what type of force system in lami’s experiment
so much helpful
thanks
Hello sir
Sir why should we only use sine angle why can’t we use cos angle or so
It is derived and we get sine
Thanks for such a valuable information
Thank you so much. Helped me a lot. God bless you.
