What Is a Parallel Force System?

Force systems are said to be parallel if the forces acting within them act in the same direction. A system in which the various forces are functioning in a manner that is perpendicular to one another is known as the antithesis of a system in which the forces are parallel to one another.

A bag of oranges is a good illustration of a force system that uses parallel forces. Although they are all situated in the same general area, the bottom of the bag, each orange is in a slightly different orientation. As a consequence of this, each has its own vector of force that is drawing it toward the centre of gravity of the earth. The person who is carrying the bag, on the other hand, does not experience each of these pressures individually. Instead, the person carrying the bag has a sensation similar to that of being pulled in a single direction due to the combination of all of the parallel pressures. The very minor disparities in the force vectors cancel each other out, and it seems as if the bag’s centre of gravity is being pulled toward the ground.

When a group of autos go across a bridge, this is another example of a force system known as a parallel force system. Gravity exerts a force that causes each automobile to move in the direction of the earth’s centre. Nevertheless, the bridge treats all of these forces as if they were a single force and records them as such. The use of this theory enables engineers to build bridges that can accommodate the combined action of all of the existing forces.
