The string provides a tension force that continuously accelerates the stone toward the center.
A block and tackle system amplifies the tension force in the rope to lift heavy loads.
Therefore, the smaller the void space, the higher water will rise due to tension forces.
The technology was also developed for anchors subject to large tension forces due to waves and stormy weather.
For example, a universal testing machine may plot the tension force on a specimen against its length.
If this were a rope, we would say that it is experiencing a tension force.
Easy at first, "ungluing" the hands becomes more difficult with every move because the tension force increases.
Thus, a magnetic tension force gives rise to a return force which is directly proportional to the displacement.
In contrast, magnetic tension force is determined by how much the magnetic pressure changes with distance.
Its weakness lies in its capability to carry tension forces and thus has its limitations.
