Lami's Theorem | Law of Triangle of Forces @qubitpune

Lami's theorem, also known as the Law of Triangle of Forces, is a principle used in statics and mechanics to determine the relationship between three concurrent forces acting on a body in equilibrium. It states that if 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 other words, if three forces u, v, and w act at a point and are in equilibrium, and the angles between them are a, b, and c respectively, then according to Lami's theorem:

u/sin(a) = v/sin(b) = w/sin(c)

This equation can be used to find the magnitude of any of the three forces, provided that the other two forces and the angles between them are known. Lami's theorem is particularly useful in resolving forces acting on a body into their components along different axes, and it can be used to solve a variety of problems in engineering and physics.
