The correct Answer is:
To solve the question, we need to fill in the blanks in the statement: "For equilibrium, the sum of all moments is equal to the sum of all __________ moments." ### Step-by-Step Solution: 1. **Understanding Moments**: - Moments (or torques) are the rotational equivalent of linear forces. They can be clockwise or anticlockwise. 2. **Equilibrium Condition**: - For an object to be in equilibrium, the total moments acting on it must balance out. This means that the clockwise moments must equal the anticlockwise moments. 3. **Defining the Terms**: - The term "sum of all moments" refers to the total moments acting on the object, which can include both clockwise and anticlockwise moments. 4. **Choosing the Correct Term**: - Since we are looking for a term that describes the moments that balance the clockwise moments, we need to use the term "algebraic" rather than "arithmetic." This is because moments are vector quantities and their direction (sign) matters. 5. **Final Statement**: - Therefore, the complete statement is: "For equilibrium, the sum of all moments is equal to the sum of all **algebraic** moments." ### Answer: For equilibrium, the sum of all moments is equal to the sum of all **algebraic** moments.
