TWO FORCES FORMING A COUPLE ARE SEPARATED BY A DISTANCE OF 25CM. IF ONE OF THE FORCES EQUALS 40N, WHAT IS THE MOMENT OF THE COUPLE

• A. 1000 Nm
• B. 500 Nm
• C. 10 Nm ✓
• D. 5 Nm
• E. 1.6 Nm

The answer to the question is: C. 10 Nm

The moment of a couple is the product of one of the forces and the perpendicular distance between the forces. In this case, the moment of the couple can be calculated using the formula:

Moment = Force × Distance

Given that one of the forces equals 40N and the distance between the forces is 25cm, we can calculate the moment of the couple as follows:

Moment = 40N × 25cm

First, we need to convert the distance from centimeters to meters as force is in Newtons and distance should be in meters for consistent units.

25cm = 0.25m

Now we can calculate the moment:

Moment = 40N x 0.25m= 10Nm

Therefore, the moment of the couple is 10Nm.
