Question

wht is static and dynamic equilibrium

Answer 1

Let's dive into the basics first.

What is equilibrium?
A body is said to be in equilibrium state when the resultant force acting on the body is zero.
So by this we can understand that if a body is in equilibrium then it might be in state of rest or in the state of constant motion.

Static equilibrium-
When the body is in the state of rest under the influence of many force then it is called as static equilibrium.
Example = Force say 10 N acting on a book on its both the sides.

Dynamic equilibrium-
When the body is motion although it is under the influence of many forces then it is known as dynamic equilibrium.
Example - Two equal forces acting at an angle of 120° is the example of dynamic equilibrium

Answer 2

Answer:

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
