Answer:
Lami's Theorem states, “When three forces acting at a point are in equilibrium, then each force is proportional to the sine of the angle between the other two forces”.In physics, Lami's theorem is an equation relating the magnitudes of three coplanar, concurrent and non-collinear vectors, which keeps an object in static equilibrium, with the angles directly opposite to the corresponding vectors. According to the theorem,where A, B and C are the magnitudes of the three coplanar, concurrent and non-collinear vectors, which keep the object in static equilibrium, and α, β and γ are the angles directly opposite to the vectors.Lami's theorem is applied in static analysis of mechanical and structural systems. The theorem is named after Bernard Lamy.
