Lami's Theorem states that if three coplaner forces acting at a point be in equilibrium, then each force is proportional to the sine of the angle between the other two forces. Mathematically
where P, Q and R are the three forces and α, β and γ are the angles as shown in Fig 1.2.

3 co-planar concurrent forces. not co-planar forces
ReplyDeleteActing at a point implies concurrent😊
DeleteS... Hence they r coplanar n concurrent forces
