4Question 4.
A couple has two forces of equal strength and direction. True or False?
- True
- False
Show hintHide hint
Consider the direction of force vectors.
Question 5.
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?
Show hintHide hint
Check if you still have a couple after the additional force is applied.
Question 6.
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.
