I made a draft demonstration of a catenary, a hanging cord with movable endpoints and changeable lentgh [1], but it's not completed; it has problems, which I am unable to fix. Is anybody interested in completing it, or helping me to complete it, and publishing it jointly on the Wolfram Demonstrations Project? Problems: - I don't know how to constrain the movements of locators under Manipulate. - FindRoot, which determines the curve shape, fails to find a solution: (1) when, understandingly, points are close to one another or one above the other, or (2) even sometimes when points are normally apart and a locator is slowly moved across. Thank you for interest, Borut Levart [1] http://demonstrations.wolfram.com/preview.html?draft/02309/000004/CatenaryTheHangingChainII
