The work of each of these forces has been presented in Sec. Work of a Variable Force If an external force F acts on a rigid body, the work done by the force when it moves along the path s, Fig.
In general, the integration must account for the variation of the force's direction and magnitude. In both cases the elevation change is considered to be small so that W, which is caused by gravitation, is constant. The work done is 18—10 where Fig. These forces can act either at fixed points on the body, or they can have a direction perpendicular to their displacement. Examples include the 8. A rolling resistance force acting on a round body as it rolls without slipping over a rough surface also does no work, Fig.
This is because, during any instant of time dt, acts at a point on the body which has zero velocity instantaneous center, IC , and so the work done by the force on the point is zero. In other words, the point is not displaced in the direction of the force during this instant. Since contacts successive points for only an instant, the work of will be zero.
To show this, consider the body in Fig.
When the body translates, such that the component of displacement along the line of action of the forces is Fig. If the body undergoes a differential rotation about an axis which is perpendicular to the plane of the couple and intersects the plane at point O, Fig. Hence, the total work done is Here the line of action of is parallel to the line of action of M. This is always the case for general plane motion, since M and are perpendicular to the plane of motion. Furthermore, the resultant work is positive when M and have the same sense of direction and negative if these vectors have an opposite sense of direction.
When the body rotates in the plane through a finite angle measured in radians, from to the work of a couple is 18—11 If the couple moment M has a constant magnitude, then 18—12 Here the work is positive provided M and are in the same direction. Also, the spring has an unstretched length of 0. Since the weight is displaced downward 1. Couple Moment M.
This checks with the result. Force P. As the bar moves downward, the force is displaced through a distance of The work is positive. Pin Reactions. Forces and do no work since they are not displaced. Total Work.
