In rigging, which factor describes how lines attach to the load?

• A. Center of gravity
• B. Estimating the weight of the object
• C. Safety considerations
• D. Angles of attachment

Answer: (D)

Angles of attachment govern how the rope segments tie into the load, and that in turn controls how the load’s force is distributed through the rigging and into the anchors. When lines attach near vertical, most of the load is carried as vertical force with smaller horizontal pull, which tends to be safer for the anchor points and makes the load path clearer. As the attachment angles spread away from vertical, the same weight requires greater tension in each line to balance the vertical component, and the horizontal components increase as well. That changes both the total forces on the rigging and the potential for sideward movement or drift of the load, so the angle of attachment directly impacts stability and safety.

Center of gravity matters for how the load behaves under motion and how it may tip or rotate, but it describes the load’s balance, not how the rigging lines connect to it. Estimating the weight of the object deals with magnitude, not the geometry of the connection. Safety considerations cover many factors, but they’re not the specific geometric descriptor of how lines attach to the load.
