Three rubber bands are shown before and after being stretched. Before stretching, bands A, B and C have lengths of 90 mm, 120 mm, and 155 mm, respectively. After stretching, band A has a length of 100 mm, while bands B and C each have a length of 200 mm. Determine the minimum normal strain in the bands.
