Lami’s theorem states that if the three coplanar concurrent forces acting on a body keep it in equilibrium, then:
Each force is proportional to the cosine of the angle between the other two forces.
Each force is proportional to the cotangent of the angle between the other two forces.
Each force is proportional to the tangent of the angle between the other two forces.
Each force is proportional to the sine of the angle between the other two forces.
Correct answer
Each force is proportional to the cosine of the angle between the other two forces.
