Equilibrium of Bodies & Concurrent Force

p {margin: 0; padding: 0;} Equilibrium of bodies forces if a body is at rest or uniform motion then it's acceleration is zero. That means The force acting on the body is zero. Body is at Forest in x axis E Fx =0 a=o Body is at rest in y-axis E Fy = 0 Body is at rest in z-axis E F2=0 concurrent force If total forces acting on a body is concurrent force. P if two concurrent forces are in equilibrium , then they're equal and opposite. if three concurrest forces are in equilibrium then the 3rd force is equal and opposite to the resultant of first two forces.
