The sum of all moment of forces in clockwise direction must be equal to sum of all moment of forces in anticlockwise direction (IF object is in equilibrium)

The sum of all moment of forces in clockwise direction aren’t necessary always equal to sum of all moment of forces in anticlockwise direction (IF object is in equilibrium)

Detailed explanation-1: -According to the principle of moments, in equilibrium sum of anticlockwise moments = sum of clockwise moments. The algebraic sum of moments of all the forces acting on the body about the axis of rotation is zero, the body is in equilibrium.
Detailed explanation-2: -If an object is balanced, the total clockwise moment about a point is equal to the total anticlockwise moment about the same point. This is called the Principle of Moments. Total clockwise moment = Total anticlockwise moment.
Detailed explanation-3: -The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point.
Detailed explanation-4: -If we take moments of the forces acting in the system about any point in the plane of the forces, then the clockwise moments will equal the anticlockwise moments if the beam is in equilibrium.
Detailed explanation-5: -If the body is in equilibrium there can be no resultant moment acting upon it; that means that the sum of the clockwise moments must equal the sum of the anticlockwise moments. This is known as the principle of moments.
