Question

describe lamis theorem

Answer 1

Lami’s Theorem:

If three forces acting on a particle keep it in equilibrium, each is proportional to the sine of the angle between the other two.

Thus if the forces are P, Q and R and α, β, γ be the angles between Q, R; R, P; and P, Q respectively then if the forces are in equilibrium, we have P/ sinα = Q/sinβ = R/sinγ

Answer 2

Idk why there're question marks above ^... seems like a glitch.
