Question: A crane operator is lifting a rectangular load using a two-leg bridle sling. The load weighs 3,000 kg. If the angle between each sling leg and the vertical is 5 degrees, what is the approximate tension in each sling leg?
Answer options:
- 1,500 kg ✅ 1,505 kg
- 1,732 kg
- 2,000 kg
Correct answer: 1,505 kg
Explanation: Using the formula Tension = (Load Weight / Number of Legs) / cos(angle from vertical), Tension = (3000 kg / 2) / cos(5°) = 1500 kg / 0.996 ≈ 1,505 kg. This slight increase from 1,500 kg occurs because even small angles from vertical increase tension.
