Unformatted text preview: ulative T-Map is a cylinder with four flattened sides and complex ends and results from the Minkowski sum of (a), (b), and (c). e) The q'-s section of the Minkowski sum (interior solid lines) of (b) and (c), together with the hexagonal Minkowski difference of the functional T-Map, which has the form of (a). The points of contact are labeled A and B. The dimensions a, b and c are represented in equation (1). Table 1.
