Answer: Not in the sense of the formulas given here. But an article on concentric bending does show the math used in the calculations: Emt Electrical Conduit Pipe Bending Instructions for Making Concentric Bends. As an example, to bend 3/4” EMT conduit have a free end height of 8.5”, the table indicates to subtract 6” from the 8.5” which leave 2.5” from the end to bend up to make the mark. Tip: Advanced benders can lay a tape measure next to the conduit and perform the bending operations if the bend does not call for high degree of accuracy. 4. CORRECTED MATHEMATICAL FORMULA .
