Deck General · Cargo Gear & SWL
As the angle between two legs of a cargo sling increases (the legs spread wider), the tension in each leg:
- ADecreases
- BStays the same
- CIncreases✓ Correct
- DBecomes zero
Explanation
The wider the included angle, the greater the tension in each leg for the same load. This is why sling angles are limited; very wide angles can overload legs rated for the load by vertical weight alone.
