In the link below, there is a force tangent to a wheel that travels distance Ds. There is also a torque that moved thru an angle. Why do they consider them equal? There are two works, shouldn't they be added together?

Or is it because in this simple case, the force travels the distance DS, but the object relative to the pivot doesn't move. This force moved thru this distance traveled because this force creates a torque which moves theta, such that work calculated linearly or rotationally are both the same.
Thank for clarification. Just trying to understand how they are the same in this case since there is both a force and torque.
