The Curved line Problem
Line Z is 8 cm long, from point x to y. Another line, Line A, is in an arc, curving from point x to y, but curving, so its highest point, in the middle, is 4 cm higher than line z. A third line, line B, arcs from point X to the middle of line Z, arcing 2 cm high. It then Arcs again from that point to point Y, arcing 2 cm high.
