Question
What is meant by equilibrium and state the conditions of equilibrium of a body?
Advertisements
Solution
When a number of forces acting on a body produce no change in its state of rest or of uniform motion the body is said to be in equilibrium.
The two conditions of equilibrium of a body:
(i) The resultant of all the forces acting on the body should be equal to zero.
(ii) The resultant moment of all the forces acting on the body about a point should be zero.
