Which concept represents the point at which the load of a weight is evenly distributed in all directions?

• A. Load weight
• B. Center of gravity
• C. Dynamic load
• D. Spelter socket

Answer: (B)

Center of gravity is the point where the total weight of a body can be considered to act, so the load is balanced in all directions. For a weight being lifted, this point is the balance point of the mass; when the lifting point lines up with or is above the center of gravity, the load stays stable and doesn’t tend to tip or rotate. If the center of gravity is offset from the lift point, sideways or rotational moments develop, making the lift uncertain and potentially unsafe. In rigging practice, you want to locate or compensate for the center of gravity so that the lifting forces align with it, keeping the load predictable and controllable. The other terms don’t describe a balance point: the load weight is just the downward force due to gravity, dynamic load refers to changing forces during movement, and a Spelter socket is a type of connector, not a balance point.
