Question

Explain Lami's theorem with example....????

Answer 1

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.

It can still be useful, though, especially when c points directly downward as when it represents the force due to a weight. See, for example, Madhukar Daftary's note on Static Equilibrium, Application of Lami's Theorem

hope it helps u\

Answer 2

Heya!!

=================================================

♦Lammi's Theorem :
=================

◾It states that the three forces acting at a point are in equilibrium if each force is proportional to the Sin Of the angle between the other two forces !!


◾If you consider there force F1 , F2 and F3 acting at a point in equilibrium and Alpha , beta and Gamma be the three angles , then =>>


$\frac{f1}{sin \alpha } = \frac{f2}{sin \gamma } = \frac{f3 }{ \sin \beta }$
