Lami's theorm

This is a short article about Lami's theorem. How to use Lami's theorem has also been discussed. This theorem is used for the solution of three vector quantities.

Lami's theorem

Lami's theorem is very helpful tool in mechanics to solve various problems that include exactly three vector quantities.

What is Lami's theorem ?

Lami's theorem states that if three co-planer forces are acting on the same point then each force is proportional to the sine of the angle between other two forces.

This formula is given as:

Consider three forces:
Let OA = F3
OB = F1
OC = F2
theorem explanation
Also note that
* Angle opposite to OA is "alpha".
* Angle opposite to OB is "Beta".
* Angle opposite to OC is "Gamma".
