Question

Q12: If two forces 5N each form a couple and the moment arm is 0.5m.Then what will be torque of the couple?​

Answer 1

Explanation:

Given: F

1

=F

2

=5N,d

1

=d

2

=0.5m

Torque τ=F×d

tau

1

=F

1

×d

1

=5N×0.5 m

=2.5 Nm (Anti-clockwise)

τ

2

=F

2

×d

2

=5N×0.5 m

=2.5 Nm (Anti-clockwise)

The resultant moment of force =τ

1

+τ

2

=2.5+2.5=5 Nm in Anti clockwise direction.

Answer 2

Explanation:

F= 5N

D= 0.5m

T=??

Formula=

T=F×D

Put the values

T=5N×0.5m

T=2.5Nm Answer.
