- Q1. 3. What is sling angle. How calculate the tension on sling during load lifting.
- Ans.
Sling angle refers to the angle between the sling and the horizontal plane. Tension on a sling during load lifting can be calculated using trigonometry.
Sling angle affects the tension on the sling - the greater the angle, the higher the tension.
To calculate the tension on a sling, you can use the formula Tension = Load / (2 * sin(angle)), where 'Load' is the weight being lifted and 'angle' is the sling angle.
It is impo...
