Question

What is Stable static equilibrium and unstable static equilibrium in short​

Answer 1

Answer:

static equilibrium means when the vector sum net external forces acting on the body is zero if the is at rest after applying static force it will be at rest only because net external force is zero..

unstable static equilibrium means when the vector sum of net external force is not equals to zero then it is said to be unstable equilibrium..

Hope it help you

Answer 2

Explanation:

In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero. By extension, a physical system made up of many parts is in mechanical equilibrium if the net force on each of its individual parts is zero
