State the Principle of Moments2 marksWhen a system is in equilibrium, the sum of the total clockwise moment is equal to the sum of the total anti-clockwise moment about the same pivot. When a system is in equilibrium, the sum of the total clockwise moment is greater the sum of the total anti-clockwise moment about the same pivot. When a system is in equilibrium, the sum of the total clockwise moment is less than the sum of the total anti-clockwise moment about the same pivot.

Why do we need to understand principle of moments2 marksTo calculate the pivotWe can calculate how to balance an unequal weight distributionTo understand the concept of balance

Write down the principle of moments

Identify the formula that represents Principle of Moments:2 marks F1 x d1 + F2 x d2 = F1 x d1 + F2 x d2 F1 / d1 = F2 / d2F1 x d2 = F2 x d1F1 x d1 = F2 x d2

Moment is a quantity that tells turning effect of a force about turning point.2 marksTrueFalse

If the moment of force at left side is clockwise and right side is anticlockwise, Bending moment is considered:*NegativeBoth negative and positivePositiveNone of above
