Drawing Out RatioAnvil Guild
Calculate final stretched length when forging down the cross-section thickness of a hot steel bar under conservation of volume.
Volume Conservation:
Total alloy volume is held constant at 187.5 cm³. Hot forging down redistributes this steel mass symmetrically along the longitudinal axis.
