In this video tutorial, Lami's theorem is been explained

Lami's theorem states that if three coplanar, concurrent and non-collinear forces are in equilibrium, the magnitude of each force is proportional to the sine of the angle between the other two forces. In this video, at first, we look at the meaning of Lami's theorem, then we considered an example and solved that with this theorem. After that we solved the same problem with conventional method and hence, proved Lami's theorem. At last, using sine law of triangle in geometry, we derived Lami's theorem.
