Explain Lami's theorem.
Answers
Answer:
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.
Explanation:
In physics, Lami's theorem is an equation relating the magnitudes of three coplanar, concurrent and non-collinear forces, which keeps an object in static equilibrium, with the angles directly opposite to the corresponding forces.
The Sine Rule is applicable only for triangles and not for all polygons. Thus, Lami's theorem is applicable for three forces, but not for any number of forces.
