Final answer:
The statement is false; the grade or slope can affect the position of the CCG, which is crucial for calculating curves on roads or bends in pipes.
Step-by-step explanation:
The statement that grade or slope will not affect the position of the CCG (Center of Curvature of Grimace) is false. The CCG, referring to the geometric point around which a curve is shaped, may indeed change its position with variations in slope or grade of the structure or element it is applied to. For example, in the context of civil engineering, the slope of a road affects how the road curves and, consequently, where the center of curvature is located. The position of the CCG is important for calculating the banking angle of a road or for pipe bending in hydraulic systems where the flow dynamics are influenced by slopes.
