THE METAL-BENDERS” by PROFESSOR JOHN B. HASTED
Many of Willie G.’s smooth parabolas were ‘abnormal plane bends’ in aluminium strip of cross-section 0.75 X 6.5 mm; they are in the plane of the long dimension, not (as would be expected) in the plane of the short dimension.
To produce such smooth bends in this plane is quite a difficult operation when achieved by normal means, for example by means of a conical roller on a flat plate. A normal parabolic bend is produced not by force applied at a single point between two supporting points (three-point load) but by a force uniform along the bent portion; this action would be produced over the central part of the specimen by a four-point load.
