In rigging terminology, CG stands for what?

• A. Center of Gravity
• B. Center of Gear
• C. Center of Load
• D. Circumference of Gravity

Answer: (A)

The main idea here is the Center of Gravity, the balance point where an object’s weight can be considered concentrated for calculations of balance and force. The center of gravity is the point at which the object would balance if supported there; for a uniform object it lies at its geometric center, while for irregular shapes it’s the weighted average of the mass distribution. In rigging, knowing the CG helps you arrange slings and the lifting point so the lift force passes near that point, keeping the load stable, minimizing rotation or side loads, and reducing uneven sling tensions during movement. The other terms don’t reflect a standard rigging concept: Center of Gear isn’t a common term for load balance, Center of Load isn’t the formal designation used for the balance point, and Circumference of Gravity isn’t a meaningful measure in this context.
