When a two-leg sling is used to lift a 20 feet load, Why is it better to use a sling 40 feet long than one of 30 feet?

🔍 Key Concepts

• Sling angle to the horizontal and how it affects tension in each leg • Relationship between sling length, load width (20 ft), and the angle formed • Basic idea that as the sling legs get more vertical, the load on each leg changes

💭 Think About

• Sketch the 20-foot load and draw two sling legs to an imaginary hook above. How does changing the sling length from 30 ft to 40 ft change the angle of each leg? • Think about what happens to the force in each sling leg when the angle from horizontal is small versus when the sling is more vertical. • Which of the answer choices directly relates to the forces in the sling rather than convenience in handling the gear?

✅ Before You Answer

• Compare the angle of the sling legs for a 30 ft sling vs a 40 ft sling on a 20 ft spread: which is closer to vertical? • Recall that smaller angles to the horizontal create much higher tension in each leg for the same load. • Decide which option refers to a mechanical advantage/safety factor rather than just operational ease.
