At what angle should tie-downs be positioned to maximize holding power?

The optimal angle for tie-downs to maximize holding power is 45 degrees. When tie-downs are positioned at this angle, they create a balance between horizontal and vertical forces, which helps to effectively secure the load. This angle ensures that the force exerted by the tie-downs is directed in a way that offers the most stability, preventing the load from shifting during transport.

Positioning tie-downs at 45 degrees allows for a more efficient transfer of holding power, which minimizes the chances of the load moving or shifting due to gravitational forces or inertial forces during movement. While other angles, such as 30 degrees or 60 degrees, may also provide some level of effectiveness, they do not optimize the balance between strength and stability in the same way that 45 degrees does.

Using tie-downs at 90 degrees would mean they are anchored directly downward, lacking the necessary horizontal component needed to keep the load secure, and likely leading to failure in holding the load effectively. Therefore, the 45-degree angle is the most effective method for achieving maximum tie-down holding power.
