Question 1
What is the formula to find the moment of a couple?
- M = F × d
- M = F / d
- M = F + d
💡 Hint: Focus on how moments are defined.
Question 2
A couple has two forces of equal strength and direction. True or False?
- True
- False
💡 Hint: Consider the direction of force vectors.

Challenge Problems
Push your limits with challenges.
Question 1
A couple consists of two forces, each of 8 N, acting 2 m apart. If one force is pulled away by an additional force of 4 N in the same direction, what will be the new moment of the couple?
💡 Hint: Check if you still have a couple after the additional force is applied.
Question 2
In a system using a couple of forces of 12 N acting at a distance of 1.5 m, determine what the moment would be if the distance were increased to 3 m while the force remains the same.
💡 Hint: Remember to apply the formula correctly and observe how changing one variable affects the outcome.
