प्रश्न
The figure shows two forces each of magnitude 10 N acting at the point A and B at a separation of 50 cm, in opposite directions. Calculate the resultant moment of two forces about the point.
- A,
- B and
- O situated exactly at the middle of the two forces.
उत्तर
Moments of force = Force × distance
F = 10 N at A and B
distance between them = 50 cm
= `50/100`
= 0.5 m
i. Moment of force at A = 10 × 0.5
= 5 N m (clockwise)
ii. Moment of force at B = 10 × 0.5
= 5 N m (clockwise)
iii. Moment of force at O = 2.5 + 2.5
= 5 N m (clockwise)
