Advanced Rigging-well answered graded A+ 2024/2025Backward stability - correct answer In crane operations, the measure of a crane steadiness in relation to the tipping axis on the opposite side of the crane from the boom. Chicago boom - correct answer A load-hoisting device con-sisting of a single boom attached at its base to either a vertical post or beam in a larger struc-ture, such as a building skeleton, or a freestand-ing pole stabilized by guy wires. Such booms are easily erected and suitable for repetitive hoisting operations at a fixed location. Center of gravity (CG) - correct answer The point where one can assume all of an object's mass, and therefore its weight, is concentrated. The con-cept is useful for determining stability, a load's balance point, and leverage. coefficient of friction (CF) - correct answer A ratio that expresses a comparison between the force nec-essary to move an object over the surface of an-other material, and the pressure between the two materials. Combined CG - correct answer The sum of the crane's and load's CGs at a position along an imaginary line connecting the two CGs Cribbing - correct answer A stack of heavy squared timbers laid in a crisscross pattern to temporarily sup-port loads during movement and placement. Dynamics: - correct answer The response of objects to the ap-plication of forces, moments, or torques. Forward stability - correct answer In crane operations, the measure of the crane's steadiness in relation to the tipping axis on the same side as the boom. Impact loading - correct answer Sudden forces acting on an object due to collisions or other dynamic events
