Lesson: Equivalent System of Forces to a Couple Mathematics
In this lesson, we will learn how to identify the conditions for a system of coplanar forces to be equivalent to a couple and find its moment.
In the given figure, if the forces that act on a light rod are equivalent to a couple, find the moment of this couple.
In the given figure, if the forces that act on a light rod are equivalent to a couple and the moment of this couple is equal to 17 N⋅cm, find and .
is a square of side length 90 cm. Forces of magnitudes of 25, 80, 25, and 80 newtons are acting along the square’s sides, and two forces, each of magnitude newtons, are acting at and as shown in the figure. Calculate the moment of the couple which is equivalent to this system, giving your answer in N⋅cm
