Equilibrium of Concurrent Forces.

Concurrent Forces: If all the forces working on a body are acting on the same point, then they are said to be concurrent.

# The necessary condition for the equilibrium of a body under the action of concurrent forces is that the vector sum of all the forces acting on the body must be zero.

#Mathematically for equilibrium or ;; ,

#Three concurrent forces will be in equilibrium, if they can be represented completely by three sides of a triangle taken in order.

# Lami’s Theorem : For concurrent forces
