Question

Two forces F, and F2 are applied on a circular body such that moment of
couple is 9 Nm in a CWD. Calculate the radius of circular body.
[30 cm]​

Answer 1

Given:-

• F1 and F2 are parallel but in opposite direction
• F1 = 15N
• F2 = 15N

To Find:-

• Calculate the radius of circular body.

Solution:

Two forces F1 = F2 are parallel but in opposite direction

As we know that,

Moment of couple = F × perpendicular distance AB

Now, putting the formula

•9Nm = 15N × 2r

where r is radius

• 9Nm = 30r

•r = 9/30

•r = 0.30m

We can also say,

• Radius is 30 cm
