Analysis of systems in mechanical Equilibrium #!#Lami Theorem #!#Concurrent Forces

Lami's Theorem

Give conditions for mechanical equilibrium.

Analysis Of Friction Force

Forces in equilibrium

Analysis of a particle in equilibrium

System is in equilibrium

A system is said to be in thermal equilibrium if

What are concurrent forces ? Obtain a condition for the equilibrium of three concurrent forces

Assertion : A body subjected to three concurrent forces cannot be in equilibrium. Reason : If large number of concurrent forces acting on the same point, then the point will be in equilibrium, if sum of all the forces is equal to zero.
