Referring to the standard format of sling load charts, the angle between the top of the load and the sling leg is called the?

• A. vertical angle
• B. included angle
• C. apex angle
• D. horizontal angle

Answer: (D)

In sling load charts, sling geometry is described using two main angles: vertical and horizontal. The angle between the top of the load and the sling leg is the horizontal angle because it is measured in the horizontal plane around the load, essentially showing how far the sling leg is spread from the load’s top when you look from above. This horizontal angle complements the vertical angle, which is the tilt of the sling leg relative to the vertical axis. Other terms like the included angle describe the angle between multiple sling legs, and the apex angle is where legs meet at the top; those are used in different parts of rigging analysis, but they don’t describe the angle between the top of the load and a single sling leg in the chart’s top-down representation.
