Question

According to principle of moments:

Options

• Sum of all the moments of force around a turning point should be zero.

• The sum of moments of force in clockwise direction must be equal to sum of moments in anticlockwise direction.

• Either sum of all the moments of force around a turning point should be zero or the sum of moments of force in clockwise direction must be equal to sum of moments in anticlockwise direction.

• None of these

Answer 1

Either sum of all the moments of force around a turning point should be zero or the sum of moments of force in clockwise direction must be equal to sum of moments in anticlockwise direction.

Explanation:

For a body in equilibrium, the algebraic sum of its moments about the turning point is zero. This also means that the total clockwise moment equals the total anticlockwise moment.
