What is the load angle factor for a sling length of 13 feet and a sling height of 9 feet?

To determine the load angle factor for a sling with a given length and height, the formula used is based on the geometry of the sling configuration. The load angle factor is calculated using the following relationship:

Load Angle Factor = (Sling Length) / (Vertical Height)

In this case, the sling length is 13 feet and the sagging height (vertical height) is 9 feet. By substituting these values into the formula, you can find the load angle factor:

1. Calculate the sine of the angle using the height and the length.
2. Determine the horizontal distance from the attachment point to the load, which relates to the geometry of the sling being used.

For a sling running horizontally and positioned at an angle, the height produces a trigonometric ratio that requires understanding the angle formed and what it means for load distribution.

After performing the calculations, you arrive at a load angle factor of 1.44. This value indicates how much additional load capacity is accounted for due to the angle of the sling in relation to the vertical lift.

Therefore, the choice that corresponds correctly to the calculated load angle factor based on the specified sling length and height is indeed 1.44.
