•Calculate the magnitude of the force of a couple which produces a moment of 21 Nm and the arm of the couple is 63 cm.
---------------------------------​

Answer 1

${\underline{\underline{\sf{Given:-}}}}$

Moment of couple = 21 Nm

Arm of couple = 63 cm = 0.63 m

${\underline{\underline{\sf{To\: find:-}}}}$

The magnitude of the force of couple.

${\underline{\underline{\sf{Solution:-}}}}$

We know that,

${\boxed{\sf{Moment\:of\: couple=F\times\:Arm\:of\: couple}}}$

Moment of couple = F × Arm of couple

$\implies\sf{21=F\times\:0.63}$

$\implies\sf{\dfrac{21}{0.63}=F}$

$\implies\sf{33.33=F}$

$\implies\sf{F=33.33}$

Hence , the magnitude of the force of a couple will be 33.33 N.

Answer 2

Answer:

Moment of couple = 21 Nm

Arm of couple = 63 cm = 0.63 m

The magnitude of the force of couple.

We know that,

Moment of couple = F × Arm of couple

Hence , the magnitude of the force of a couple will be 33.33 N.
