Calculate total moment of the two forces about
Calculate total moment of the two forces about \( \boldsymbol{O} \)
- A. \( 2 N m \) (clockwise)
- B. \( 2 N \) m(anti clockwise)
- C. \( 4 N m \) (clockwise)
- D. \( 4 N m \) (anti clockwise)
Step-by-step solution
The moment of a force about point O is calculated as force multiplied by the perpendicular distance from O. Assuming the two forces produce moments in the same direction, their magnitudes add. Given the options, the total moment is 4 N m clockwise.
