Enter the sling height and sling length into the calculator to determine the sling angle in degrees.
Sling Angle Formula
The following formula is used to calculate the angle of a sling.
SA = arccos(H/L)
- Where SA is the sling angle (degrees)
- H is the height of the sling
- L is the length of the sling
To calculate the sling angle, take the inverse cosine of the height divided by the length of the sling.
What is a sling angle?
Definition:
A sling angle is a measure of the angle between the centerline of a sling and the length of either side of the sling.
How to calculate sling angle?
Example Problem:
The following example problem outlines how to calculate the angle of a sling.
First, determine the height of the sling. This is the distance from the surface of the hanging object to the center of the sling. In this case, the height is 5 inches.
Next, determine the length of the sling. In this example, the length of the sides of the sling is 8 inches.
Finally, calculate the sling angle using the formula above:
SA = arccos(H/L)
SA = arccos(H/L)
SA = 51.283
