• This is a programme for studying the shape of a bow formed by joining the ends of a flexible, slender, elastic rod using a flexible string.
• The shape depends on the ratio of H, the length of the string, to L, the length of the rod.
• There is also the discrete problem, in which a rigid rod of length L is divided into N + 1 equal parts which are connected by N joints, each joint having identical torsional springs.
• Scroll down to see the controls. Use the sliders for H/L and N. If you type in H/L, use the Update button.
• Other Symbols: α: angle between rod and string at the tie, b: distance from the middle of the rod to the string,
