- Static Equilibrium: A stationary object is a special case of mechanical equilibrium and called to be in static equilibrium. Thus, it is defined as; “a body is said to be in static equilibrium if it is at rest under the action of several forces acting together on the body”.
Example: Consider a book resting on the table. Two forces are acting on the book; one its weight ‘w’ acting downwards and the normal reaction of the surface of the table. However, the book is at rest. Therefore, the two forces cancel one another and there is no unbalanced force on the book. No acceleration is produced in the book and it is in ‘static equilibrium’.
Smart notes thnku sir
Thank you so much, Afaq.
