In shared-anchor systems, what happens to the force as the angle created by the force vector narrows?

In shared-anchor systems, as the angle created by the force vector narrows, the components of the force acting in the direction of the anchor become more effective. The effective force can be understood through basic principles of physics, particularly vector resolution. When the angle between the force vector and the line of action decreases, the component of the force acting along that line also increases, thereby enhancing the overall effectiveness of that force in maintaining tension or stability in the system.

This phenomenon is rooted in trigonometry, where if you consider the angle approaching a straight line, the cosine of the angle tends to increase towards one, meaning that the force vector projects more of its magnitude along the relevant direction. Consequently, with a narrower angle, a larger portion of that force contributes to the desired outcome in a shared-anchor configuration, hence the force experienced by the anchors effectively increases as this angle narrows. This principle is critical in engineering and physical applications where force directionality determines system stability and load management.
