What is the effect of a small lashing angle (e.g. angle alpha < 30 degrees to the load floor) in Force-Locking Tie-Down Lashing (Niederzurren)?

1. The strap becomes ten times stronger automatically
2. The cargo becomes completely weightless
3. The effective downward vertical pretension force is severely reduced, requiring a massive increase in the number of lashing straps to achieve statutory securing force
4. The lashing angle has zero mathematical effect on tie-down clamping force
