// Inputs for Bend Angle Tonnage required
// Material Type:L A
// Tensile Strength (if known) in Mpa
// Material Thickness
// K-Factor
// V die opening (print suggested v opening of 8x material thickness)
// Radius
// Minimum Flange
// {[(575 × Material thickness squared) / Die width] / 12} × Material factor

// Outputs for Bend Angle Tonnage
// P in kN/mt and convert to Tons (lb^2/i)
