The given equation represents which of the following?

\(\rm\frac{A}{\sin \alpha}=\frac{B}{\sin \beta}=\frac{C}{\sin \gamma}\)

The correct answer is option 3):(Lami's theorem)

Concept:

• LAMI’S Theorem states, “If three coplanar forces acting at a point be in equilibrium, then each force is proportional to the sine of the angle between the other two.”
• Consider three forces F1, F2, F3 acting on a particle or rigid body making angles α, β, and γ with each other.

\(\rm\frac{A}{\sin \alpha}=\frac{B}{\sin \beta}=\frac{C}{\sin \gamma}\)

Additional Information

• Lambert's law of absorption states that equal parts in the same absorbing medium absorb equal fractions of the light that enters them
• The equilibrium law states that the concentrations of the products multiplied together, divided by the concentration of the reactants multiplied together, equal an equilibrium constant (K)
• The superposition theorem states that a circuit with multiple voltage and current sources is equal to the sum of simplified circuits using just one of the sources.
