Question

A FORCE OF 25N ACTS ON A BODY SUCH THAT THE COUPLE ARM IS 60CM. CALCULATE THE MOMENT OF COUPLE IN S.I SYSTEM?

Answer 1

Answer:

15N

Explanation:

60cm=60/100m

M.O.C=F*arm of couple

=25*60/100

15N

Answer 2

Concept:

The product of either force and the angle between the lines of action of the two forces is the moment of couple.

Given:

Force= 25N

Couple arm= 60cm

To find:

Moment of couple

Solution:

As we know,

Moment of couple$= Force * Couple of arm$

$= 25 \times 60 N-cm$

$= \frac{1500}{100} Nm= 15Nm$

The moment of couple is 15Nm.
