Haha, I get it. the title is the formula for determining Bend Allowance, which is a factor used in determining the length of a flat piece of sheet metal required to form to specific dimensions after it is bent.
The formula results in the length of the cord at the neutral line of the bend. It varies depending on sheet thickness (T) the inside radius of the bend ® and the angle the sheet is bent at (A). Locating the neutral line requires K-factor (K), which requires another formula (and usually some testing) to determine.
BA=A(Pi/180)(R+KxT)
